The firebox is designed to accept a 3/8-inch gas line for an approved
ventless 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 8
. 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 9.
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 LP fireboxes to reduce the
supply tank pressure to a maximum of 14" w.c. This is in addition
to the regulator fitted to the log set.
WARNING: CONNECTION DIRECTLY TO AN UNREGULATED
L.P. TANK CAN CAUSE EXPLOSION.
Install only a ANSI Z21.97.1/CSA 2.41 ventless log set into this
firebox.
