GENERAL INFORMATION:

When the heater is cold, it will take a few minutes for

the burner tile to turn bright orange. This is normal and

the heater is working properly. If burner tile is visibly

flaming, turn heater off and call a qualified service

technician.

When the unit is lit, there should be about a quarter

inch border around the tile that will not turn bright

orange. This is normal.

When operating the heater for the first time, the top

area of the reflector may discolor. This is also normal

and is no reason for concern.

sea level, the unit may not burn as bright as in lower

altitudes. This is normal. At higher altitudes, the heater

may shut-off. If this happens, provide fresh air, wait 5

minutes and re-light. If the heater continues to shut

off, there may not be enough oxygen available to feed

proper combustion.

Operating time will be approximately 5 1/2 hours on

a one 1lb cyclinder. Due to the properties of LP gas,

runtimes can be significantly reduced when operating

This heater is equipped with a tip-over safety switch.

Nuisance shut-downs may be experienced if the unit

is bumped or moved. If this occurs simply relight the

heater.

• Due to natural operation of small tanks, condensation

may build up on tank and drip on surface under heater.

Sometimes this condensation may freeze due to the

extreme cold caused when propane vaporizes. This is

normal and no reason for alarm.

A slight yellow flame may occur where the pilot flame

and main burner flame meet. The burner should be bright

orange (with a slight blue color around the border, a red-

orange haze that is visible on the ceramic tile is acceptable)

and without a noticeable flame.

A blue flame that rolls out at the top of the ceramic tile

indicates an accumulation of dust, lint or spider webs

inside the housing assembly and main burner assembly.

If the pilot is yellow or the burner has a noticeable flame,

cleaning may be required. Use the following procedure to

inspect the casing assembly and main burner assembly. It

is necessary to periodically check the burner orifice and

burner venturi to make sure that they are clear of insects/

nests or spider webs that may accumulate over time. A

clogged tube can lead to a fire.
