Inspect/prepare installation site
Chimney or vent
•
Inspect the chimney or vent, making sure it is properly sized and in good
condition for use.
•
For those installations not requiring a chimney, such as through-the-wall vented
appliances, follow the instructions given by the appliance and power venter (if
used) manufacturers.
Direct air supply and sidewall venting
•
Some AFG burners are equipped with combustion air boots to allow use of
outside air for combustion.
•
When sidewall venting appliances, carefully follow appliance and power venter
instructions for installation and wiring.
Combustion air supply
See NFPA Standard 31 for complete details.
If the burner is not supplied with a reliable combustion air source,
the burner cannot properly burn the fuel. This would result in incomplete com-
bustion, causing sooting and possible emission of carbon monoxide. Severe
personal injury, death or substantial property damage could occur.
Appliance located in confined space
The confined space should have two (2) permanent openings: one near the top
of the enclosure and one near the bottom of the enclosure. Each opening shall
have a free area of not less than (1) one square inch per 1,000 BTU’s per hour
of the total input rating of all appliances within the enclosure. The openings shall
have free access to the building interior, which should have adequate infiltration
from the outside.
Exhaust fans and other air-using devices
Size air openings large enough to allow for all air-using devices in addition to the
minimum area required for combustion air. If there is any possibility of the
equipment room developing negative pressure (because of exhaust fans or
clothes dryers, for example), either pipe combustion air directly to the burner or
provide a sealed enclosure for the burner and supply it with its own combustion
air supply.
Outside air kit applications
Refer to separate instruction sheet supplied with AFG outside air kit for installation.
This optional kit allows combustion air to be piped directly to the burner. (Part
number 51747.)
You must install the outside air kit strictly following the kit instal-
lation instructions. Do not attempt to install outside air piping without using the
AFG outside air kit and instructions. Failure to do so could result in burner or
heating appliance failure, causing potential severe personal injury, death or sub-
stantial property damage.

Clearances to burner and appliance
•
Provide space around burner and appliance for easy service and mainte-
nance.
•
Check minimum clearances against those shown by the appliance manufac-
turer and by applicable building codes.
Combustion chamber — Burner retrofitting
Verify that the appliance combustion chamber provides at least the minimum
dimensions given in Table 2.
When retrofitting an appliance that has a stainless steel chamber
— A chamber burnout could result from the use of a high performance burner.
Protect the chamber from high temperatures through the use of "wet-pac" or a
similar ceramic liner. Some new equipment may contain stainless steel cham-
bers that have been designed and tested by the manufacturer for use with flame
retention burners — ceramic protection would not be necessary. Refer to appli-
ance manufacturer’s instructions. Failure to comply could result in damage to
heating equipment.
