minimum of 6 inches water column.
The supply system must supply 8” WC
min. (RA100NGDGD) for each heater
connected to the system.
Check with your local gas supplier to
properly size all of your supply lines. Be
sure to follow all local codes, or refer to
the Natural Fuel Gas Code Handbook –
NFPA54/ANSI Z223.1, or the Natural Gas
Installation Code – CAN/CSA B149.1.

A three square foot
opening of fresh
outside air for each 100,000 BTU/Hr of
heater output must be provided to
operate each heater safely. If the proper
ventilation air is not provided, carbon
