Ventilation
A minimum building ventilation rate of 4 CFM per 1000 BTU'S of installed heater
input must be provided. This rate of ventilation may be obtained through either gravity or
mechanical ventilation of the building. In conjunction with building ventilation system, ade-
quate fresh air into the building must be provided through fresh air inlets and/or building
inlets. It is recommended local code be checked to assure the ventilation system and heat
installation are in compliance with local and/or state code
When checking for gas leaks, do not use an open flame. Use a soap and water
solution. Installation of 1/8
” NPT plugged tapping, accessible for test gage connections, is
required upstream of the gas supply connection to the heater. NOTE:
Gas connections on
the heater are leak tested at the factory prior to shipment.
Precautions:
●
Periodically check the whole gas system for leaks or immediately check if the smell of
gas is detected. Extinguish all open flames
●
