PLANNING THE INSTALLATION

In planning the installation for the replace it is necessary to determine where the unit is to be installed and whether optional accessories are desired. Gas supply piping should also be planned. The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence.

1. Position fireplace in desired location. Refer to the Fireplace and Framing Dimensions (page 6, Figures 2 and 3,) Fireplace Location (page 8, Figure 5) and Clearances and Height Requirements (page 9, Figures 6 and 7.)

NOTE: Be sure all cardboard packing material has been

removed from under the unit.

2. Install following the instructions found in this manual.

3. Field wire main power supply to junction box. Refer to the Electrical Installation section (page 13). (Electrical connections should only be performed by an experienced, licensed certied service person).

4. Plumb gas line. Refer to the Connect the Gas (page 11, Figure 10) section found in this manual. (Gas connections should only be performed by an experienced, licensed/certied service person).

5. Complete nish wall material and/or surround.

ADEQUATE COMBUSTION AND VENTILATION AIR

This heater shall not be installed in a conned space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

The National Fuel Gas Code, (ANSI Z223.1/NFPA54), denes a conned space as a space whose volume is less than 50 cubic feet per 1,000 BTU per hour (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space, and an unconned space as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors, are considered a part of a conned space.

Unusually tight construction is dened as construction where:

a. Walls and ceilings exposed to the outside atmosphere

have a continuous water vapor retarder with a rating of 1 perm (6 x 10 gasketed or sealed, and

b. Weather stripping has been added on openable win-

dows and doors, and

kg per pa/sec-m2) or less with openings

c. Caulking or sealants are applied to areas such as joints

around window and door frames, between sole plates and oors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical and gas lines and other openings.

The following formula can be used to determine the maximum heater rating per the denition of unconned space:

BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft

Consider two connecting rooms with an open area between, with the following dimensions:

L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.

BTU/Hr = (151/2 + 12) x (12) x (8)

If there were a door between the two rooms the calculation would be based only on the room with the heater.

BTU/Hr = (151/2) x (12) x (8)

to placing any reglass or stone media on the burner. To install the air deection glass simply place the tabs (located at the bottom of the glass) into the slots at either end of the burner oor, in front of the burner ports. The glass should stand upright, neither leaning forward nor backward. Repeat for the second glass deector installation.

FIREGLASS ONLY PLACEMENT

NOTE: Two (2) bags of reglass are supplied with the

replace. Both bags may be used to cover the entire oor and burner. We advise against using additional reglass as too much can cut off the proper amount of air the burner needs to burn cleanly. This may cause sooting.

1. Spread reglass evenly in one layer over the entire oor and burner. It is important to not have the reglass too thick on ported area (single layer only).

2. Turn burner on and adjust reglass over ported areas to achieve an even, clean ame.

GLASS AND OPTIONAL STONE KIT PLACEMENT

1. For best results, spread reglass evenly over the entire oor and burner making sure the reglass is not too thick over the burner ports (single layer only).

2. Place the stones randomly in front of and behind the air deection glass. CAUTION: Do not allow stones to sit directly on burner or in ame. Figure 16.

3. Turn burner on and adjust reglass over the ported area to achieve an even, clean ame. (page 27, Figure

32.)

SYSTEM CONFIGURATION/SETUP

All System conguration/setup is done on the Command Center.

NOTE: When using On/Off wall switch, the switch must be in the ON position to perform all conguration set ups at the command center.

COLD CLIMATE OPTION

Choose the Mode That Best Suits Your Needs The Signature Command® System is designed to operate

in either Standing Pilot or Intermittent Pilot mode.

• The Standing Pilot Mode is best for colder climates

when the pilot must remain on continuously to prevent condensation and ensure reliable operation.

• The Intermittent Pilot Mode is ideal for maximum ef-

ciency, igniting the pilot only when needed to start your replace, lowering fuel consumption and reducing your carbon footprint.

Either mode benets from the instantaneous battery backup, so you never have to worry about a power outage.

NOTE: The Signature Command® System comes standard in the Intermittent Pilot mode, so you must follow the instructions below to switch to Standing Pilot Mode if needed.

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 ames visually during operation.

CHECK THE PILOT FLAME

The pilot ame must always be present when the

heater is in operation. It should just touch the top of the thermocouple tip for natural gas. Refer to Figure 30 for correct pilot ame.

If the pilot ame does not touch the thermocouple, then the main burner cannot function reliably. Refer to Figure 31 for incorrect shape of pilot ame.

OPERATING INFORMATION

Avoid any drafts that alter burner ame patterns. Do

not allow fans to blow directly into the replace. Do not place a blower inside the burn area of the rebox. Ceiling fans may create drafts that alter ame patterns. Sooting and improper burning will result.

During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, lms, 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.

This appliance must not be used with glass doors.

Choose the stylish rustic stone kit or go minimalist with just a coating of crushed glass and transform the replace to suit your space.

NOTE: Rope lighting kits can only be installed on the wide contemporary faces listed below.
