Connecting The Gas - Monessen Hearth VDY24/18 Installation And Operating Instructions Manual

Use new black iron pipe, steel pipe, copper tubing, or internally tinned copper tubing.
Copper or internally tinned copper tubing can only be used according to the National
Fuel Gas Code, section 2.6.3, providing gas meets sulfide limits, and where permitted
by local codes. Gas piping system must be sized to provide minimum inlet pressure
(listed on Data Plate) at the maximum flow rate (BTU/Hr). Undue pressure loss will occur
if the pipe is too small.
A manual shutoff 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.
Refer to Figure 5.

IMPORTANT: Hold appliance regulator firmly with a wrench to prevent movement when connecting to inlet piping.
Check gas type: The gas supply must be the same as stated on the gas logs rating plate. If the gas supply is different, DO
NOT INSTALL THE GAS LOGS. Contact your dealer for the correct model.
Always use an external regulator for all propane/LPG gas logs only, to reduce the supply tank pressure to a maximum of
13" w.c. This is in addition to the regulator fitted to the gas log set. High pressure natural gas systems require a regulator to
reduce supply pressure to 10" W.C.
