Section: General Information
Do NOT Alter the Original
Burner Design
Tampering with or altering the burner design could
seriously impair performance, resulting in loss of
static pressure, damage to the system components,
reduced air volume, heavy smoke, flame
impingement, appliance sooting, hot gas puff-back,
and asphyxiation or fire hazards.
Maintain the design to its original configuration.
Only use parts specified for AF or AFG Burners.
Do NOT remove the air guide from the AFG chassis.
Do NOT use ‘M’ Series air tube combinations on AF
Burners.
Never try to convert an AF to an AFG or vice versa
Any design alteration will:
y
Void UL Listing
y
Void manufacturer’s warranties
y
Seriously impact burner performance
y
Greatly increase your liability risk
Impaired Burner Performance
and Fire Hazard.
Do NOT operate the burner beyond specifications
outlined in the following Table.

NOTE: Some packaged appliances with burners
may be agency listed as a unit to operate beyond
these limits. Consult the appliance manufacturer’s
specifications and agency approvals for verification.
If the residence is unattended in severely cold
weather, burner primary control safety lockout,
heating system component failures, power outages
or other electrical system failures could result in
frozen plumbing and water damage in a matter of
hours. For protection, take preventive actions such
as having a security system installed that operates
during power outages, senses low temperature
and initiates an effective action. Consult with your
heating contractor or a home security agency.
