VENTILATION
WARNING: FOLLOW THE MINIMUM FRESH, OUTSIDE
AIR VENTILATION REQUIREMENTS. IF PROPER
FRESH, OUTSIDE AIR VENTILATION IS NOT
PROVIDED, CARBON MONOXIDE POISONING
CAN OCCUR. PROVIDE PROPER FRESH, OUTSIDE
AIR VENTILATION BEFORE RUNNING HEATER.
Provide a fresh air opening of at least three square feet for
each 100,000 Btu/Hr rating. Provide extra fresh air if more
heaters are being used.
PROPANE SUPPLY
Propane / L.P. gas and Propane / L.P. tank(s) are to be
furnished by the user.
Use this heater only with a propane vapor withdrawal
supply system. See Chapter 5 of the Standard for Storage
and Handling of Liquefied Petroleum Gas, ANSI/NFPA 58
and the Propane Installation Code CAN/CGA B149.2. Your
local library or fire department will have this booklet.
The amount of Propane / L.P. gas ready for use from
Propane / L.P. tanks varies. Two factors decide this amount:
1. The amount of Propane / L.P. gas in tank(s)
2. The temperature of tank(s)
The chart below shows the number of 100 pound (45 kg)
tanks needed to run this heater. Smaller tanks can be used
for limited run times but it is recommended to use larger
tanks for optimum performance.
Less gas is vaporized at lower temperatures. You may need
two or more 100 pound (45 kg) tanks or one larger tank in
colder weather. Your local Propane / L.P. gas dealer will
help you select the proper supply system. The minimum
surrounding air temperature rating for each heater is
-20° F (-29° C).
