Fireplace Installation - MHSC BBV400 Installation And Operating Instructions Manual

FIREPLACE INSTALLATION

Only persons licensed to work with gas
piping may make the necessary gas
connections to this appliance.
NOTE: The gas line connection may be made using 1/2" rigid tubing or an approved flex con-
nector. Since some municipalities have additional local codes, it is always best to consult your
local authorities and the current edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54. In
Canada CSA-B149 (1 or 2) Installation Code.
A listed manual shut-off valve must be installed upstream of the appliance. Union tee and plugged 1/8"
NPT pressure tapping point should be installed upstream of the appliance. Figure 15
IMPORTANT: Install main gas valve (equipment shut-off valve) in an accessible locations. The main
gas valve is for turning on or shutting off the gas to the fireplace.
Check your building codes for any special requirements for
locating equipment shut-off valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will pre-
vent excess sealant form going into pipe. Excess sealant in
pipe could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg in
supply line as shown in Figure 15. Locate sediment trap/drip
leg where it is within reach for cleaning. Install in piping system between fuel supply and burner system.
Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap traps mois-
ture and contaminants. This keeps them from going into the burner system gas controls. If sediment
trap/drip leg is not installed or is installed wrong, burner system may not run properly.
