Preparation
Before beginning, remove glass door and logs from
unit. Also check to make sure there is no hidden
damage 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 9)
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, 1/2" 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.
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.
When using copper or flex connector, use only
approved fittings.
Always provide a union when
using black iron pipe so the gas line can be easily
disconnected for burner or fan servicing. See gas
specifications for pressure details and ratings. NOTE:
If flex connector is used, it must be kept inside of the
heater.
These gas inserts are approved for installation
in solid fuel burning masonry or zero clearance
fireplaces.
