ventilation air, this heater may give off excessive
CARBON MONOXIDE, an odorless, poisonous gas.
Some people - pregnant women, persons with heart
or lung disease, anemia, those under the influence of
alcohol, those at high altitudes - are more affected by
carbon monoxide than others.

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.

Mr. Heater MH4GC Golf Cart Heater 4
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.
CLEANING INSTRUCTIONS:
1. Allow heater to thoroughly cool before performing
any maintenance.
2. Remove disposable 1 lb. propane cylinder from
heater.
3. Remove right side plastic service panel (Parts diagram
ref. 4) by removing the four screws holding it in
place.
4. Inspect the interior of casing for accumulation of
dust, lint or spider webs. If necessary, clean the
interior of the casing assembly with a vacuum cleaner
components within the casing assembly when you
are cleaning.
5. Inspect and clean main burner (Parts Diagram ref. 3)
and orifice (ref. 8) by using a vacuum or compressed
6. Inspect and clean pilot tube (Parts Diagram ref.
7). Insert a doubled over pipe cleaner into the
pilot tube until it bottoms against the pilot orifice
of times and remove. Blow out the remaining debris
using compressed air.
