If left unsealed, drafting may cause pilot outage or sooting. Use a heat resistant sealant. Do not seal the chimney flue damper. WARNING Before installing in a solid fuel burning fireplace, The chimney fl ue and firebox must be cleaned of soot, creosote, ashes and loose paint by a qualified chimney cleaner. INSTALLING VENTED APPLICATIONS Manual and 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. WARNING This appliance is for installation only in a solid fuel burning fi replace (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. This log set may be installed as a vented log set. 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. Install and operate the appliance as directed in this manual. DAMPER STOP INSTALLATION: A damper stop must be provided with the unit. Contact your dealer to obtain one. The damper stop must be installed as shown in Figure 13 to prevent full closure of the fireplace damper blade and provide a minimum 29 square inch flue opening. DamperStopDamper Figure 13 - Damper Stop Installation. (See WARNING at top of next page.) 18 44D0060 INSTALLING VENTED APPLICATIONS WARNING 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 WARNING 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 fi replace. 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 11. 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 two (2) 5/32" diameter holes approximately 11/2" deep. 3. Anchor the grate to the fireplace/firebox floor using the screws provided. See Figure 14. Proper installation of the grate is essential to prevent any movement of the gas logs and controls during operation.

Consult all local codes. CAUTION Use new black iron or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Code, section 2.6.3, providing gas meets hydrogen sulfide limits, and where permitted by local codes. Gas piping system must be sized to provide minimum inlet pressure (Listed on Data Plate) at the maximum flow rate (BTU/Hr). Undue pressure loss will occur if the pipe is too small. A manual shutoff valve must be installed upstream of the appliance. Union tee and plugged 1/8" NPT pressure tapping point should be installed upstream of the appliance. See Figure 15.

CAUTIONCHECK GAS TYPE: The gas supply must be the same as stated on the heater’s rating plate. If the gas supply is different, DO NOT INSTALL THE HEATER. Contact your dealer for the correct model. Always use an external regulator for all propane/LPG heaters and high pressure one to two-pound systems only, to reduce the supply tank pressure to a maximum of 13" w.c. This is in addi...
