PROPER BURNER FLAME
A proper flame will have a dark blue inner mantle
that sits right on top of the burners with a lighter
blue outer mantle rising above the burner, (See
Figure 11). There may be some yellow where the
pilot flame and burner flame meet. There is no
primary air adjustment on the burner, and proper
flame is assured since the correct manifold pressure
and orificing has been done at the factory. NOTE:
It is advised that the burner flames be checked at
least twice during the heating season for any changes
in burner flame characteristics. The appliance area
must be kept clear and free from combustible
materials, gasoline, and other flammable vapors and
liquids. This heater comes from the factory with
the proper burner orifice for elevations up to 2,000
feet. Heaters installed above 2,000 feet must be
derated 4% for every 1,000 feet. For the proper
orifice size find the Model Number and elevation
on the orifice chart (See CONTROLS). Replace
burner orifice.

OPERATION
This unit uses a “step open” valve. When heat is
called for the gas valve opens at a reduced manifold
(outlet) pressure to insure a safe, quiet ignition.
After 10 – 20 seconds the valve automatically steps
up to normal manifold outlet pressure to provide
proper BTU input for the remainder of the heat
cycle.

After the heat exchanger has warmed sufficiently,
the fan will automatically come on to efficiently
transfer the heat into the room. NOTE: All but the
35,000 BTU unit (which is one speed) have an
automatic two-speed fan. In a new installation or
on fall start-up in a very cold room, some on-off
cycling of the fan may occur if the heat exchanger
cools too much. The burner, however, will continue
to operate and the fan cycle until the thermostat is
satisfied.
