Unusually tight construction is defined as con- struction where:
a)Walls and ceilings exposed to the outside atmosphere have a continuous water vapour retarder with a rating of 1 perm (6 x
b)Weather stripping has been added on openable win- dows and doors, and
c)Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between
An unvented room heater is recommended for use as a secondary heat source rather than as a primary source. Gas combustion produces water vapour which could occur at the rate of approximately one ounce of water for every 1,000 BTU/hr of gas input. During the cold weather season, indoor humidity levels tend to be low. Consequently, this water vapour can enhance the living space. However if a problem should occur:
a)ensure suffi cient combustion and circulation air
b)use a dehumidifi er
c)do not use the unvented room heater as a primary heat source
Without suffi cient fresh air for proper operation, poor fuel combustion can result. Carbon Monoxide is a result of poor combustion.
If additional fresh air is required, use one of the meth- ods described in the National Fuel Gas Code, ANSI Z223.1, Section 5.3 or the applicable local code.

GAS INSTALLATION
Proceed once the vent installation is complete.
NOTE: All gas connections must be contained within the fireplace when complete.
1.Move the fi replace into position and secure to the fl oor through the 1/4" holes located at either side of the base.
2.The fi replace is designed to accept 3/8" gas supply line. The fi replace is equipped with a 3/8" manual
3.Connect the gas supply in accordance to local codes. In the absence thereof, install according to the National Installation Code.
4.When fl exing any gas line, support the gas valve so that the lines are not bent or kinked.
5.Check for gas leaks by brushing on a soap and water solution.
DO NOT USE OPEN FLAME.
OPTIONAL WALL SWITCH
INSTALLATION
For ease of accessibility, an optional remote wall switch may be installed in a convenient location. A 20’ length of millivolt wire is connected to the gas valve for the wall switch. How- ever if a greater length is required route
