The firebox is designed to accept a 3/8-inch gas line for an approved
vent-free gas logset. Have the line installed by a qualified service
person in accordance with all building codes. Consult local building
codes to properly size the gas supply line leading to the 3/8-inch
hook-up at the unit. The state of Massachusetts requires that a
flexible appliance connector cannot exceed three feet in length.
Gas access holes are provided on both sides of the firebox.
See
Figure 11.
On models with refractory brick panels installed, carefully
remove the knockout in the refractory brick panel using a large
standard screwdriver and hammer. First, place screwdriver in groove
next to plug and pry sideways to pop out main plug. Then remove
the remaining concrete in hole with gentle tapping with ball peen
hammer and/or screwdriver. A masonry drill and bit may also be
used to create a clean hole for the gas line to pass through.
See
Figure 12.
When installing optional ceramic fiber side panels into firebox,
lay panel on a flat surface. Remove the gas line knockout (round
depression) in the appropriate side panel using a drill or utility knife.
After the brick panel knockout is removed, the firebox wrap may
have a round metal knockout that must be removed also. Use a
screwdriver to punch out the metal knockout.
Check gas type. Use only the gas type indicated on the gas log
set rating plate. If the gas listed on the plate is not your type of gas
supply, DO NOT INSTALL. Contact your dealer for proper model.
Always use an external regulator for all Propane fireboxes to reduce
the supply tank pressure to a maximum of 14 inch w.c. This is in
addition to the regulator fitted to the log set.
WARNING
Connection directly to an unregulated propane tank can
cause explosion.
Install only a ANSI Z21.11.2 vent-free log set into this firebox.
