My apologies for the sketch. My laptop with 2D and 3D software needs repair. I will continue my original plans to vent the chambers outdoors. I did not complete the installation due to it was to be for odor control and the twin carbon filters work fine themselves. I will treat explosion and CO poisoning together as they share the same flow:
Here is some information:
Propane Combustion Characteristics Explained
In order for propane to burn, ignite or go through combustion, the criteria listed above must be met. Below are explanations of propane gas combustion characteristics.
Propane Limits of Flammability - The lower and upper limits of flammability are the percentages of propane that must be present in an propane/air mixture. This means that between 2.15 and 9.6% of the total propane/air mixture must be propane in order for it to be combustible. If the mixture is 2% propane and 98% air, there will not be combustion. If the mixture 10% propane and 90% air, combustion will not occur. Any percentage of propane in a propane/air mixture between 2.15% and 9.6% will be sufficient for propane to burn. However, an improper air/gas mixture can produce Carbon Monoxide (CO) that is a deadly product of incomplete combustion. Flash Point - The flash point is the minimum temperature at which propane will burn on its own after having been ignited. This number states that below -156°F, propane will stop burning on it’s own. In other words, if the outside air temperature is -155°F, propane will burn on it’s own. If the outside air temperature falls to -157°F, propane will no longer burn on it’s own. However, if a source of continuous ignition is present, propane will burn below - 156°F. Ignition Temperate in Air - This number states that propane will ignite if it reaches a temperature between 920-1020°F. If propane is heated up to a temperature between 920 and 1020°F, it will ignite without needing a spark or flame. Maximum Flame Temperature - A propane flame will not burn hotter than 3595°F. Octane Number - Without presenting a chemistry lesson, the Octane number of propane being over 100 means that it is a very engine friendly fuel.
Carbon Monoxide (CO) is responsible for almost 25% of all propane related fatalities. Carbon Monoxide is the product of incomplete gas combustion often because appliances are improperly adjusted. Properly functioning propane appliances will produce what is called an “ideal burn” during combustion and present no danger of Carbon Monoxide poisoning. Carbon Monoxide poisoning can lead to severe injury and even death.
Three ingredients required for combustion to take place include fuel, ignition and air. Without any one of these three ingredients, combustion will not occur and even still, the ratio of air to gas must be within an acceptable range for combustion to occur. For instance, a mixture made up of equal parts propane and air will not combust when ignition is introduced. With propane, combustion will occur when the gas in air mixture is between 2.2 and 9.6 and is referred to as the “limits of flammability”. In other words, 2.2 parts propane and 97.8 parts air is a combustible mixture as is 9.6 parts propane and 90.4 parts air. Combustion will occur anywhere between these two gas to air ratios with the “ideal burn” being about 4 parts propane and 96 parts air (1:24). This ideal ratio is considered to be the most efficient burn of propane gas when used. Complete combustion of propane is evident by a blue burning flame.
Incomplete Propane Combustion - Carbon Monoxide
Carbon Monoxide is produced during the incomplete combustion of propane. Incomplete combustion is defined as within the limits of flammability but higher or lower than the ideal ratio of 4 parts propane 96 parts air. Incomplete propane combustion can occur in one of two ways:
Lean Burn - The ratio of propane to air is less than 4 parts propane. 2.5 parts propane to 97.5 parts air would produce a lean burn. A lean burn can be recognized when flames appear to lift away from the burner and can potentially go out.
Rich Burn - A ratio of propane to air is more than 4 parts propane. 8.5 parts propane to 91.5 parts air would produce a rich burn. Recognizing a rich burn is very simple as the flames are much larger than they are supposed to be and are largely yellow in color.
Several products of incomplete combustion that are easily visible and if noticed, action should be taken immediately. Visible signs of incomplete combustion include burner flame appearance (as listed above), soot collecting on appliance windows such as that of a space heater and excessive water vapors forming on windows and cool surfaces during appliance operation. Appliance service and adjustment is needed if any of these visible signs of incomplete combustion are noticed.
First Alert CO615 Carbon Monoxide Plug-In Alarm with Battery Backup and Digital Display
Plug-in carbon monoxide alarm with battery back-up and digital display
Uses electrochemical carbon monoxide sensor–the most accurate technology available
Simple to use silence/test button
Low battery warning; end-of-life timer
Includes two AA batteries; 7 year limited warrantyK
Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don’t know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you’re in danger at first. That’s why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can’t see, smell or taste in the air.
The First Alert CO615 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. Installation is as simple as plugging it in to any wall outlet. Its easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. The alarm includes a battery back-up giving you peace of mind in a power outage. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit’s functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. An audible and visual low battery signal alerts you to replace the battery and an indicator alerts you when a battery has been removed. An end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 7-year limited warranty. UL listed.
Liquid Propane (LP) 4 Burner CO2 Generator
Liquid Propane (LP) 4 Burner CO2 Generator
In nature, plants combine water, carbon dioxide (C02), and light into chemical energy that can be used to fuel the plant’s growth and flowering. This process of photosynthesis can be augmented and accelerated by the introduction of more carbon dioxide into a growing environment. Due to an increased C02 intake, plants grow much faster and stronger.
This Liquid Propane (LP) 4 Burner C02 Generator is constructed of resilient powder coated steel. Its precision manufactured clean firing brass burners are rated to cover a 20ft x 20ft (400 sq ft) growing area. A featured solid state electronic ignition module eliminates the need for pilot lighting and the unit features an easy On/Off switch. Hanging hardware is included, as well as a power cord and gas hose with an intake regulator.
4 Burner unit is recommended for a 20ft x 20ft area (400 sq ft) (Grow Room = 240 sq ft.)
Unit is compatible with Liquid Propane (LP) only

I will resume the installation of a 4" exhaust from the grow room to the outdoors. It was originally designed for odor control until the twin carbon filters work fine themselves and vent into the house. Ducting in place.
Thank, all input is greatly appreciated, positive and negative
I hope it’s nit too jumbled as copying and pasting on this iPAD sucks.
