v. L1

• 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.

THE STATE OF CALIFORNIA REQUIRES THE FOLLOWING WARNING:

WARNING:

Combustion by-products produced when using this product contain carbon monoxide, a chemical known to the State of California to cause cancer and birth defects (or other reproductive harm).

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.

Mr. Heater | MHGLLP B MHGLLP G Operating Instructions and Owner’s Manual

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 tieon mantles, #20353. Or “Pre-formed” type burner head, #20337, with pre-formed mantles, #20351.) Also see “Mantle Installation and Lighting Instructions.”

Burner Head Screen. Screen must be in threaded end of burner

head. Gaslight will not function properly if screen is missing.

Seal. Seal is placed on threaded end of burner head. Seal and burner head should be screwed securely into Bunsen Burner Venturi (BBV.) The seal must be replaced any time the burner head is removed after the lamp has been used.

Note: Always replace seal if lamp has been previously lit.

GASLIGHT LOCATION, MOUNTING, & ASSEMBLY

WARNING:

Read all instructions and Gaslight Warning Tag (attached to light) before installing light. Make sure that the gas supply is turned OFF at the supply tank and that the gaslight valve handle is in the ‘OFF’ position.

Use “Tie-on” type burner head, #20352, with tie-on

mantles, #20353

Bunsen Burner Venturi (BBV). Flow of combustion air and ventilation air must not be obstructed. To ensure proper air flow and gas mixture, the inside of the BBV must be clean and free of any material that may potentially accumulate, such as spider webs, insects, etc. Make a periodic visual check of the BBV. The BBV can be cleaned by drawing a clean, dry cloth through it. It can also be cleaned by blowing it out with compressed air. Never attach a mantle directly to the BBV.

Plumbing Supplies

The following plumbing supplies are needed for installation. They are available from your local gas dealer.

Copper Tubing

Internally tinned copper tubing, outside diameter, is recommended. Copper tubing must be internally tinned to meet National Fuel Gas Code unless otherwise directed by local codes.

Fittings

If 3/8” copper tubing is used, a 3/8” Flare Male Connector x

/8 NPT Straight Fitting is required. Mr. Heater #20347 (included).

If Gaslight is to be connected from behind (through wall) a

/8 NPT Street Elbow (Male-Female), Mr. Heater #20348 (included)

must be used in addition to the Straight Fitting.

Permanent screws that attach valve assembly to wallplate should never be loosened or removed. Removing valve assembly from wallplate will void warranty.

Location of Indoor Gaslight

Always mount gaslight on an open wall. Never mount gaslight in a boxed-in or recessed area.

Wall Bracket Assembly (Ref. #1) must be mounted so that Heat Deflector (Ref. #15) is a minimum of four inches from a combustible surface, and outside of Globe (Ref. #13) is a minimum of three inches from a combustible surface to either side or in front. Mounting gaslights too close to a door may subject delicate mantles to vibrations and could damage the mantle.

Assembly

First, remove all packaging materials from gaslight.

1. Remove Wall Bracket Assembly (Ref. #1) and visually identify Valve Assembly (Ref. #2) and Orifice (Ref. #4). From center of Orifice, measure a minimum of seven inches below an overhead combustible surface and a minimum of ten inches from a combustible surface at the front. These dimensions will provide the minimum clearance to combustible surfaces for the Heat Deflector and Globe. DO NOT TOUCH, DISTURB OR DAMAGE HOLE IN ORIFICE, even oil from hands can interfere with proper gas flow.

If gas supply is to be connected through bottom of Valve Cover (Ref. #27), remove Knockout tab (twist out using pliers) in valve cover before proceeding.

2. Connect internally tinned copper tubing to Gas Inlet (Gas Inlet) using proper fitting (See “Fittings” page 3). It is easier to connect the tubing before fastening Wall Bracket Assembly to wall (also Wall Bracket Assembly is less likely to be bent). Valve Assembly (Ref. #2) must be straight on the Wall Bracket Assembly. Orifice (Ref. #4) must aim into the center of the BBV (Ref. #28) for proper air and gas mixture.

3. Fasten Wall Bracket Assembly to wall using four mounting screws (Ref. #26) supplied. CAUTION; DO NOT OVER-TIGHTEN SCREWS. The four Bosses (Mounting Bosses) on the Wall Bracket Assembly must not be imbedded in the wall because air must circulate behind the Wall Bracket Assembly to prevent scorching.

Replacement parts and accessories are available from your local gas dealer or from Mr. Heater, Inc.

MANTLE INSTALLATION & LIGHTING INSTRUCTIONS

Do not use defective mantles (holes, etc.) Replace defective mantles immediately.

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. After gaslight has been properly installed and thoroughly checked for leaks by qualified gas personnel only:

1. Remove globe.

2. a. Pre-formed mantle: Grasp ceramic ring – do not touch mantle itself. Hook legs into reverse “L” of the burner head.

b. Optional Tie-on mantle: Loop the tie-on strings at the throat

of the mantle. Work fingertips into mantle throat and enlarge the opening so that it will fit over the ceramic burner head and seat in lower groove of burner head. Do not tie the mantle to the BBV. Distribute puckers in the mantle evenly around the burner head. Pull the ends of the string snugly so that mantle and string are seated securely in the burner head groove. Tie a double knot and clip off excess string.

Optional “Tie-On”

Not Included

4. Attach Valve Cover Assembly (Ref. #27) to Wall Bracket Assembly by engaging Slots (Slots) with Wall Bracket Assembly Tabs (Assembly Tabs).

5. Carefully swing down the Valve Cover Assembly so that the slots in the bottom of valve cover engage Lock Screws (Ref. #12). Tighten Lock Screws.

6. Check the following dimensions:

Minimum of 4 inch clearance from top of Heat Deflector (Ref. #15) to ceiling.

Minimum of 3 inch clearance from outer edge of Globe to both sides and front.

Ensure 1 Holder (Ref. #16).

7. Loosen Globe Lock Screw (Ref. #14) and remove Globe. Be sure that all packaging material has been removed. Attach mantle.

8. Attach Globe after installing mantle but before burn-off (See “Mantle Installation and Lighting Instructions”) by engaging Tabs (Globe Holder Tabs (2)) and inserting Globe so that Globe Lock Screw can be tightened into the neck of the Globe. Do not overtighten.

3. Replace globe.

4. Mantle burn off: WITH GASLIGHT VALVE HANDLE IN THE

“OFF” POSITION, and in a well ventilated room, hold a lighted match close to, but not touching, bottom of mantle. Remove match when mantle begins to smolder. Allow fabric to burn completely.

NOTE: It is normal for mantles to smoke during burn-off procedure.

WARNING:

After burn-off, mantle is a chemical ash. It will break if touched. Upon lighting of gaslight, it will shrink to its final form.

5. Lighting of gaslight: Light gaslight only after mantle burn-off

(Step 4) has been completely accomplished. Caution: Do not turn gaslight to “ON” position until after lighting match. Do not touch mantle with the match.

Note: When gaslight is newly installed, air may be present in the gas line. Several matches may be required before the gaslight will light. After a new mantle is ignited, allow it to burn for five to ten minutes so it will shrink to its final form. Gaslight is now ready for use.

6. Turning gaslight off: To turn off, simply move gaslight valve handle to the “OFF” position.

LIGHTING GASLIGHT

Light gaslight only after mantle burn-off (Step 4) has been completely accomplished.

Caution: Do not turn

gaslight to “ON” position

until after lighting match.

When gaslight is burning

properly, flame is bright white and has no visible

outlines.

Turn gaslight to “ON” position. Do not touch

mantle with the match.

To turn off, simply move

gaslight valve handle to

the “OFF” position.
