INSTALLING AS A VENTED APPLIANCE Manual and millivolt 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. 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 9) to prevent full closure of the fireplace damper blade and provide a minimum 29 square inch flue opening. State of Massachusetts requirement for installation of vented decorative appliance in a vented fireplace is the following: A vented decorative gas appliance must be installed in a vented fireplace only in the state of Massachusetts. The vent damper must be removed or welded permanently open. Damper Stop Installation Figure 9 12409-2-0403 Page 10 BEFORE FULLY INSTALLING THE APPLIANCE BEFORE FULLY INSTALLING THE APPLIANCE • 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. 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. Metal shipping plate covering burner marked REMOVE must be removed from top of burner and discarded. Burner will not operate if plate is left in place. Save for future use – when servicing fireplace. Assembly Procedure: (Figure 10) 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. An anchor hole is provided in the two bottom side members of the grate frame. After centering the grate correctly, mark the hole positions on the fireplace/firebox floor. Drill two (2) 5/ 32" diameter holes approximately 1-1/2" deep for masonry screws or 1/8" hole for sheet metal screws. 3. Anchor the grate to the fireplace/firebox floor using the screws provided. Refer to Figure10. Proper installation of the grate is essential to prevent any movement of the gas logs and controls during operation.
