Gas Fireplace Insert

Combustion Air

It is very important that an adequate air supply is available when the unit is being operated. Since most homes of today are tightly sealed and insulated, addi- tional make-up air is usually necessary.

This fireplace has been designed to operate by drawing air in from the front and outer perimeters of the fire- place. The air provides combustion air ensuring a clean burning flame, dilution air for proper venting, as well as the air which the fan circulates over the firebox/heat exchanger system.

NOTE: Insulating around the fireplace will result in overheating and possible malfunctioning of the circulat- ing fan.

Zero Clearance Applications

An alternate air supply is recommended with this component.

For installation other than in existing woodburning fire- places such as new construction or renovation projects, a Zero Clearance Kit must be used. The kit enables these inserts to be installed in combustible environ- ments. Whenever using a Zero Clearance Kit, consid- eration must be given to the dimensions of the Zero Clearance Kit and the requirements of the Air Kit when planning out the installation.

Do not use this appliance if any part of it has been under water. Immediately call a qualified service technician to inspect the unit and replace any part of the control which has been under water.

High Elevations

Input ratings are shown in BTU per hour and are certified without deration for elevations up to 4,500 feet (1,370m) above sea level.

For elevations above 4,500 feet (1,370m) in USA, installations must be in accordance with the current ANSI Z223.1/NFPA 54 and/or local codes having jurisdiction.

In Canada, please consult provincial and/or local authorities having jurisdiction for installations at elevations above 4,500 feet (1,370m).

These gas inserts are approved for installation in solid fuel burning masonry or zero clearance fireplaces.

Preparation

Before beginning, remove glass door and logs from unit. Also check to make sure there is no hidden dam- age to the unit. Take a minute and plan out the gas, venting and electrical route. It is best to start with the gas line first followed by the chimney liner. (Refer to Page 8)

Gas Line Installation

When purging the gas line, the front glass must be removed.

If gas piping from the source to the heater location has not been accomplished, install the required pipe. Consult local plumbing code to assure proper pipe size.

The gas pipeline can be brought in through the rear or the base of the heater.

NOTE: The gas line connection can be made of either properly tinned 3/8" copper tubing, 3/8" rigid pipe or an approved flex connector then reduced to 3/8" to the heater. Some municipalities have additional local codes, it is always best to consult your local authority and the CSA- B149.1 installation code.

U.S. Installations consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

The gas control inlet is 3/8” N.P.T. therefore the 1/2” rigid gas line must be reduced to 3/8” N.P.T. A typical installation layout for rigid pipe is shown in Figure 4.

Always check for gas leaks with a mild soap and water solution. Do not use an open flame for leak testing.

The gas control is equipped with a captured screw type pressure test point, therefore it is not necessary to provide a 1/8" test point up stream of the control.
