.WARNING
DANGER OF ILLNESS
BODILY INJURY OR DEATH
THE FURNACE AND ANY OTHER FUEL BURNING
APPLIANCE MUST BE PROVIDED WITH ENOUGH
FRESH AIR FOR PROPER COMBUSTION AND
VENTILATION OF FLUE GASES. MOST HOMES
WILL REQUIRE THAT OUTSIDE AIR BE SUPPLIED
INTO THE FURNACE AREA.
WARNING
DANGER OF PROPERTY DAMAGE,
BODILY INJURY OR DEATH
EVEN WHEN HOUSE MEETS REQUIREMENTS
FOR UNCONVINED SPACE WITH ADEQUATE AIR
INFILTRATION IT IS RECOMMENDED THAT A
FRESH AIR INTAKE BE INSTALLED TO LESSEN
THE POSSIBLE DANGERS FROM ANY FUTURE
CHANGES ON THE HOME.
VENTING
WARNING: This heater is equipped with a vent safety shut-off system to protect against improper venting of its combus-
tion products. Tampering with or removal of this control will void the limited warranty and can result in carbon monoxide
(CO) poisoning and possible death.
A. An effective flue is necessary to carry off water vapor, carbon monoxide (CO), carbon dioxide (CO2), and other
products of combustion. For proper venting, follow the following basic rules for gravity venting, which are:
S.
C.
D.
1. Keep the flue gases hot.
2. Follow the vent manufacturer's installation instructions.
3. Select the proper vent size.
4. Provide constant fresh air replacement.
For new installation, it is recommended that a Type "B" vent in accordance with its listing be used. A Type "B"
vent is one made of non-combustible, corrosion resistant material of sufficient thickness and cross sectional area
and heat insulating quality to avoid excess temperature on adjacent combustible material and certified by a na-
tionally recognized testing agency. Existing brick flues should be lined to provide an effective vent. Brick chimneys,
even in good repair, may be too large and will not provide sufficient draft to effectively vent a heater.
Use vent pipe of the same size as the outlet on back of heater. In no case should a smaller vent be used.
Avoid a horizontal run of vent pipe whenever possible. When a horizontal run is necessary, the pipe must pitch
upward at least 1/4"to the foot, and must be supported securely and joints fastened by sheet metal screws or rivets.
Under no circumstances should the vent run downhill.
E. Never put a damper or barometric draft control in a gas vent pipe.
F. Never end a vent in an open attic or run vent through a wall to the outside without extending it upward above the roof.
G. Always terminate vent with an approved cowl.
H. WARNING: ALWAYS SECURE VENT PIPE TO OUTLET ON BACK OF HEATER WITH A SHEET METAL SCREW.
IMPORTANT:
Inspect venting system prior to each heating season.
