The connection of Model MH35LP to an LP-Gas cylinder must
be made in a well ventilated area using the regulator and hose
assembly supplied with the appliance. DO NOT attempt to adjust
this regulator. It has been preset at the factory to provide safe and
proper operation of the appliance. Use a 7/8” open end wrench
to connect the POL fitting (supplied with the LP regulator) to the
LP-Gas cylinder. Turn the POL nut in a counter-clockwise direction
(left hand thread) until tight. DO NOT use pipe compound on POL
threads.
The heater must be located at least six feet away from any LP-Gas
cylinder and must not be directed toward any LP-Gas cylinder
within 20 feet. If more than one heater is used, they and the
supply cylinders must be separated by at least 20 feet.
The gas supply must be turned off at the LP-Gas supply cylinder
when the heater is not in use.
When the heater is to be stored indoors, the connection between
the LP-Gas supply cylinder and the heater must be disconnected
and the cylinder removed from the heater and stored in
accordance with chapter 5 of the Standard for the Storage and
Handling of Liquefied Petroleum Gases, ANSI/NF-PA 58 (U.S.), OR
CAN/CGA B149.2 (Canada).
If connected to a permanently installed LP Gas supply system, the
system requires the use of a two-stage gas regulator assembly
which is normally provided by your LP-Gas dealer as part of the
LP-Gas supply system. Consult with your local LP-Gas dealer for
details concerning proper equipment and installation.
Piping must be clean and free from scale or burr.
Before attempting to ignite the appliance, all gas fittings and
connections must be thoroughly checked for gas leaks. Apply a
small amount of a mild soap and water solution to all fittings and
connections and observe for escaping bubbles. If any leaks are
detected, shut off the gas supply to the appliance immediately.
Wait a minimum of five minutes, repair the leak(s) and retest for
leakage. Dry all fittings and connections after leak testing.
WARNING
NEVER USE A fLAmE fOR GAS LEAK TESTING.

LIGHTING AND SHUT-DOWN
lighting the Heater:
1. Before attempting to light the heater, smell all around
the heater area for gas. Be sure to smell next to the floor
because LP-Gas is heavier than air and will settle on the
floor. Turn on the gas supply to the appliance and check
all fittings and connections for gas leaks using a mild
soap and water solution. NEVER use a match to check
for gas leaks. Should a gas leak occur, shut off the gas
supply to the appliance immediately. Wait a minimum of
five minutes before repairing the leak.
2. Use only the fuel intended for this appliance. Check the
appliance rating plate for the correct fuel information.
3. Turn off the main gas supply to the appliance. Wait five
minutes.
4. Turn on the main gas supply.
5. Depress red spark ignition button repeatedly or with
a lighted match held to the burner face, depress and
hold the reset button on the safety valve. After the
burner ignites, hold the reset button depressed for
about one minute or until the burner stays lit when
the reset button is released.
dO nOt light the gas
at the burner orifice. dO nOt face heater when
attempting to light. always stand to the side of the
unit when lighting
.
NOTE: In cases where long runs of gas supply lines have been
installed ahead of the appliance, it may be necessary to bleed
trapped air out of the supply lines before lighting the burner.
New installations generally require bleeding of supply lines.
Wait a minimum of five minutes after bleeding the supply
lines before attempting to light the heater.
