M38DV-ST / ME38DV-ST Direct Vented Fireplace

Maintenance

General

n Have the fireplace installation inspected yearly, including a visual

check of the vent system, the burner and the pilot flame. For your

convenience a 1/8" manifold pressure tap is supplied on the gas

valve for a test gauge connection. See Figure 6.

n For Natural Gas this appliance requires a minimum inlet pressure

of 5.5" W.C. and a manifold pressure of 3.5" W.C.

n For Propane Gas this appliance requires a minimum inlet

pressure of 11" W.C. and a manifold pressure of 10" W.C.

n Always keep the fireplace area clear and free of combustible

materials, as well as gasoline and other flammable vapours and

liquids.

n Do not use this appliance if any part has been under water.

Immediately call a qualified service technician to inspect the

appliance and to replace any part of the control system and any

gas control which has been under water.

CAUTION

• Fireplace gas control must be in the “OFF” position and pilot

and main burners extinguished when cleaning appliance with

a vacuum.

• Glass and logs can get very hot. Handle only when cool.

Cleaning

When the fireplace is first activated, there may be some smoking and

a visible film may be left on the glass. This is a normal condition, and

is the result of burningthe protective coatings on new metal.

n Glass must be cleaned periodically to remove any film (a normal

bi-product of combustion) which may be visible. Film can easily

be removed by removing the door, as shown on page 12. Handle

the door carefully, and clean it with non-abrasive glass cleaners.

One of the most effective products is Kel Kem.

n Silicone seals on inner door during initial firing will "off gas",

leaving a visual deposit of a white substance on combustion

chamber walls. This can easily be removed by following the steps

described above.

n Use a vacuum cleaner or whisk broom to keep the control

compartment, burner, and firebox free from dust and lint.

n Logs may be cleaned periodically with a vacuum to remove soot.

WARNING:

Do not attempt to clean glass when hot.

Do not clean glass with abrasive materials as any glass

etching may cause premature glass failure.

Pilot Burner Adjustment

1. Locate Pilot Adjustment Screw. (See figure 21.)

2. Turn Adjustment Screw until flame is proper size. (See figure 22).

3. After installing or servicing, leak test with a soap solution with main

burner on. Coat pipe and tubing joints, gasket etc. with soap

solution. Bubbles indicate leaks. Tighten any areas where the

bubbles appear until the bubbling stops completely.
