Mr. Heater | MHGLLP B MHGLLP G Operating Instructions and Owner’s Manual
• The design of Models MHGLLP B and MHGLLP G are C.S.A.
certified. Installation must conform with local codes or, in the
absence of local codes, with the National Fuel Gas Code, ANSI
Z223.1 (latest edition), and/or with CAN1-B149.2 (latest
edition) installation code for propane burning appliances and
equipment, and local codes.
IMPORTANT INFORMATION FOR USING
MR. HEATER INDOOR GASLIGHTS
• Use Gaslight only for purposes of illumination. Installation and
repair of equipment that operates on propane gas is a job for
experts. Do not attempt to install or repair your gaslight unless
you have been thoroughly trained and are experienced in such
matters. If your gaslight appears to be malfunctioning, turn it
to the “OFF” position and immediately contact your local dealer
or the Mr. Heater factory.
• After installation and before use, have qualified gas personnel
approve your installation and check for gas leaks using a leak
detector. Tubing, fittings, gaslight valve and any other gas
transporting component should be checked. Subjecting valve
assembly to testing pressures in excess of 6 PSI can damage
sealing grease which can cause leaks and voids warranty.
WARNING:
Use your gaslight in vented rooms only.
Carbon monoxide is produced by the incomplete
combustion of fuel.
WARNING:
Do not store or use gasoline or other flammable vapors
and liquids in the vicinity of this or any other appliance.
RECOMMENDED MAINTENANCE
The following matters should be dealt with as frequently as
necessary. If your gaslight has been out of use for a period of
time, examine it before lighting it.
Keep area clear and free from combustible materials, including
gasoline and other flammable vapors and liquids. Flow of
combustion air and ventilation air must not be obstructed.
Use propane gas only for models MHGLLP B and MHGLLP G.
Propane gas must be to this rating: 2500 to 2530 B.T.U. per cubic
foot. Mr. Heater propane gas orifices are manufactured to this
pressure rating only. See “Gaslight Rating Label.”
Propane gas supply tank and regulator. Gas supply tank must
not be overfilled. Regulator must be adjusted to operate at a
pressure of 11 inches of water column (27.9 cm) (6 oz. of mercury).
This same gas pressure must be maintained at the orifice of the
gaslight. Higher or lower pressures will cause the gaslight to
malfunction.
Copper gas tubing. Copper gas tubing must be internally tinned
to meet National Gas Code Standards unless otherwise directed by
local codes.
Orifice. All gaslights are equipped with standard propane orifices.
To use gaslights at elevations of 4500 feet or more above sea
level, order High Altitude Orifice, #20368 for propane gas.
WARNING:
Never touch drilled hole in orifice, as it is extremely
delicate. Use low-pressure compressed air to clean the
orifice. Pins, wire, even oil from hands, may disturb proper
gas flow. Replace orifice if in question.
Both MHGLLP B and MHGLLP G are ready to use with
PROPANE ONLY, at altitudes under 4,500 ft. The following
gas orifices are available for these other applications:
FUEL TYPE GAS ORIFICE
PROPANE (High Altitude) 20368
Valve Assembly. The valve assembly must be straight on the wall
bracket. Bracket can become cocked or bent when tightening
copper tubing, flare nut, etc. causing orifice to be aimed crooked.
Gas flow through the orifice must be aimed straight down the
center of the BBV.
When gaslight is operating properly, gas consumption is 2100
B.T.U. per hour. One “pound” of propane gas produces
approximately 10 hours of light.
Permanent screws that attach valve assembly to wallplate should
never be loosened or removed. Removing valve assembly from
wallplate will void warranty.
Mantles. Use Mr. Heater mantles which are designed for use with
propane gas only. Never use broken mantles. Inspect for carbon
deposits each time gaslight is used. Clean or replace defective
mantles immediately. Use proper ceramic burner head and mantle
combination. (Example: “Tie-on” type burner head, #20352, with tie-
on mantles, #20353. Or “Pre-formed” type burner head, #20337,
with pre-formed mantles, #20351.) Also see “Mantle Installation
and Lighting Instructions.”
