IMPORTANT SAFETY INFORMATION

Continued from page 3

14. Caution: Candles, incense, oil lamps, etc. produce combustion byproducts including soot. Vent-free appliances will not filter or clean soot produced by these types of products. In addition, the smoke and/or aromatics (scents) may be reburnt in the vent-free appliance which can produce odors. It is recommended to minimize the use of candles, incense, etc. while the vent-free appliance is in operation.

15. This is an unvented gas-fired heater. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventilation air must be provided. See page 7.

16. Keep room area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

17. Unvented gas heaters are a supplemental zone heater.

They are not intended to be the primary heating appliance.

18. Unvented gas heaters emit moisture into the living area. In most homes of average construction, this does not pose a problem. In houses of extremely tight construction, addition mechanical ventilation is recommended.

19. During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or bonding agents. These chemicals are not harmful but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance; possibly causing headaches or eye or lung irritation. This is a normal and temporary occurrence.

The initial break-in operation should last two to three hours with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in period will be slight and will disappear with continued use.

20. Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. For elevations above 2,000 feet, input ratings should be reduced 4 percent for each 1,000 feet above sea level. Refer to the National

Fuel Gas Code.

21. The heater and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

22. The heater must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig

(3.5 kPa).

23. Do not use this room heater if any part has been under water. Immediately call a qualified service technician to inspect the room heater and to replace any part of the control system and any gas control which has been under water.

FIREPLACE PREPARATION

BEFORE FULLY INSTALLING THE UNIT:

• Turn OFF the gas supply to the fireplace or firebox.

• Seal any fresh air vents and/or ash clean-out doors located on the floor or wall of the fireplace. If left unsealed, drafting may cause pilot outage or sooting. Use a heat resistant sealant. Do not seal the chimney flue damper.

Before installing in a solid fuel burning fireplace, The chimney flue and firebox must be cleaned of soot, creosote, ashes and loose paint by a qualified chimney cleaner.

INSTALLING VENTED APPLICATIONS

Milli-volt controlled gas logs may be installed as a vented decorative log set in compliance with ANSI Z21.60 and

National Fuel Gas Code, Section 6.6. Since the gas logs are operated with the damper open, non-combustible material and minimum mantel requirements do not apply.

This appliance is for installation only in a solid fuel burning fireplace (masonry fireplace or manufactured fireplace) with a working flue and constructed of noncombustible material.

Exception: DO NOT install this appliance in a factory-built fireplace that includes instructions stating that it has not been tested or should not be used with unvented gas logs.

BEFORE INSTALLING THE APPLIANCE:

• Turn off gas supply to fireplace or firebox.

• Have the fireplace floor and chimney professionally cleaned to remove ashes, soot, creosote or other obstructions.

Have this cleaning performed annually after installation.

• Seal any fresh air vents or ash clean-out doors located on floor or wall of fireplace. If not, drafting may cause pilot outage or sooting. Use a heat-resistant sealant. Do not seal chimney flue damper.

Install and operate the appliance as directed in this manual.

DAMPER STOP INSTALLATION:

A damper stop must be provided with the unit when used for vented applications. Contact your dealer to obtain one. The damper stop must be installed as shown in Figure 11 to prevent full closure of the fireplace damper blade and provide a minimum 29 square inch flue opening. For installation in the Commonwealth of

Massachusetts, see Note 27 on page 4.

INSTALLING VENTED APPLICATIONS

The fireplace and gas logs function as a system. If the fireplace is spilling into the room (check with a match or a smoke stick), reposition the damper clamp until a positive draft is obtained by opening the damper. If negative pressure in home prevents having a positive draft, contact your dealer for assistance.

PLACING AND SECURING APPLIANCE

You must secure the gas log heater to the fireplace floor. If not, the entire unit may move when you adjust the controls. Movement of unit may cause shifting of the gas logs which leads to sooting and improper burning. Grate movement could cause a gas leak.

Special care is required if you are installing the unit into a sunken fireplace.

You must raise the fireplace floor to allow access to gas log controls. This will insure adequate air flow and guard against sooting. Raise the fireplace floor using noncombustible materials, as described in “PLACEMENT IN A FIREPLACE WITH

RESTRICTIVE BARRIER” on page 10.

ASSEMBLY PROCEDURE:

1. Center the gas log unit in the fireplace or firebox. Make certain the front feet of the grate sit inside the front edge of the fireplace or firebox.

2. Anchor holes are located on the right and left sides of the unit. After centering the grate correctly, mark the hole positions on the fireplace/firebox floor. Drill four (4) 5 /

32

" diameter holes approximately 1 1 /

LOG PLACEMENT

Before you begin — This unit is supplied with one ceramic fiber log. Do not handle the log with your bare hands.

Always wear gloves to prevent skin irritation from ceramic fibers. After handling the log, wash your hands gently with soap and water to remove any traces of fibers.

The positioning of the logs are critical to the safe and clean operation of this heater. Sooting and other problems may result if the logs are not properly and firmly positioned in the appliance. Never add additional logs or embellishments such as pine cones, vermiculite or rock wool to the heater. Only use the logs supplied with the unit.

Failure to position the parts in accordance with diagrams below or to use only parts specifically approved for this heater may result in property damage or personal injury.

INSTALLING LOG ON GRATE (See Figure17)

Carefully place one-piece log on grate over two logpositioning pins as shown.

Pins

PLACING THE DECORATIVE ROCK

DO NOT sprinkle volcanic rock on the logs or around the pilot or the main burner. This may cause sooting. Place volcanic rock only on the floor of the fireplace.

During initial operation of the new heater, burning logs will give off a paper burning smell and orange flames will be present. Simply open the windows for a few hours to vent the odor.

Figure 17 - Installing Logs to Grate

22 43D0122 43D0122 23

FLAME APPEARANCE

Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed.

In addition, periodically check the flames visually during operation.

CHECKING THE PILOT FLAME

The pilot flame must always be present when the heater is in operation. It should just touch the top of the thermocouple tip for natural. Refer to Figure 18 for correct pilot flame.

If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. Refer to Figure

19 for incorrect shape of pilot flame.

CHECKING THE BURNER FLAME

In normal operation at full rate after 15 minutes, the following flame appearances should be observed:

Figure 20 - Correct Appearance of Flames

The flames should be yellow and extend 3"-4" above the log top surfaces. The yellow flames should not contact the logs.

OPERATING INSTRUCTIONS

Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the fireplace. Do not place a blower inside the burn area of the firebox. Ceiling fans may create drafts that alter flame patterns. Sooting and improper burning will result.

During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance, possibly causing headaches or eye or lung irritation. This is a normal and temporary occurrence.

The initial break-in operation should last two to three hours with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in will be slight and will disappear with continued use.This appliance must not be used with glass doors in the closed position. This can lead to pilot outages and severe sooting outside the fireplace.
