Combustible mantles may be installed above the appliance (as shown in Figure 2 ). The mantle projection may be extended beyond 8" if the height above the firebox opening is in- creased proportionately as detailed by the in- crements shown.

Minimum clearance to combustibles are:

Appliance:	each side - 1/2”
	floor - 0"
	adjacent wall - 0"
	ceiling - 37-1/2” (953 mm)
	0" Clearance

A hearth extension is not required with this appliance. If a hearth extension is used, do not block the lower control compartment door. Any hearth extensions used is for appearance only and does not have to conform to standard hearth extension installation requirements.

Note: Combustible wall finish materials and/or surround materials must not be allowed to encroach the area defined by the appliance front face (black sheet metal). Never allow combustible materials to be positioned in front of or overlapping the appliance front face.

PREINSTALLATION

Check that all listed parts have been received.

Carefully inspect the heater case and contents for shipping damage and immediately inform the dealer from whom you purchased the gas fireplace if any damage is found.

The appliance is shipped with all gas controls and components installed and pre-wired. Re- move the shipping carton, exposing the screen panel assemblies or optional (if installed) glass doors. Remove wood slats and remove and discard the wood slat mounting brackets. Loosen and remove the three (3) 1/4"-20 x 1" Phillips pan head screws at the three (3) tabs located along the top of the screen or glass door frame top edge. Tilt the frame outward and disengage the three (3) tabs along the bottom from the three (3) brackets at the bottom of the firebox opening. Remove the door and set the panel aside protecting it from inadvertent dam- age. Retain the three (3) screws for use on reassembly. Repeat the procedure (if required) to gain access to the other side of the appliance. Remove the logs, packaged inside the firebox and also set aside.

Check Gas Type

This appliance can only be connected to the gas type specified on the appliance data plate. This appliance can not be modified in the field for a different gas type. If the gas type to be used is not the one specified contact the dealer to obtain the correct gas appliance.

Note: Illustrations shown in this manual reflect “typical” installations with nominal dimensions and are for design and framing reference only. Actual installations may vary due to individual design preferences. However, always maintain minimum clearances to combustible materials and do not violate any specific installation re- quirements.

Note: The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence.

CAUTION: HEATERS CREATE WARM AIR CUR- RENTS. THESE CURRENTS MOVE HEAT TO WALL SURFACES NEXT TO HEATER. INSTALL- ING HEATER NEXT TO VINYL OR CLOTH WALL COVERINGS OR OPERATING HEATER WHERE IMPURITIES IN THE AIR (SUCH AS TOBACCO SMOKE) EXISTS, MAY DISCOLOR WALLS.

ASSEMBLY STEPS

The typical sequence of installation follows, however, each installation is unique resulting in variations to those described.

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.

1. Construct the appliance framing.

2. Route gas supply line to appliance location.

3. Install nailing flanges. Install the hoods.

4. Position the appliance within the framing and secure with nailing brackets.

5.Make connection to gas supply.

6.Assemble the Carbon Monoxide Safety Shutoff (COSS).

7.Install the operating control switch and bring in electrical service line for forced air circulat- ing blower (optional equipment).

8.Mount forced air kit (optional equipment).

9.Install the logs and Rockwool.

10.Checkout appliance operation.

11.Install screen assembly or (optional) glass door.

INSTALLATION STEPS

Built-In Systems

WARNING: DO NOT ALLOW FANS TO BLOW DIRECTLY INTO THE FIREPLACE. AVOID ANY DRAFTS THAT ALTER BURNER FLAME PATTERNS.

WARNING: DO NOT USE A BLOWER IN- SERT, OR OTHER ACCESSORY NOT APPROVED FOR USE WITH THIS HEATER.

Do not burn solid fuels in this listed unvented gas room heater.

Note: Appliance Dimensional Specifications are shown in Figure 3.

Step 1. Frame the VFST appliance as illus- trated in Figures 4 and 5.

The header may be in direct contact with the top metal spacers, but must not rest on them or be notched to fit around them.

Step 2. Route a 1/2" (13 mm) gas line along the left or right side framing (Figure 6 ). The primary method for the SF is from the right end (when viewed from the control side) straight in to the valve. ST's may be routed as the PF's are, from the left using an assembly composed of a 3/8" street elbow, a 3/8" elbow and 3/8" 6" long nipple.
