Leak Testing - OCI OCIE48EH Installation & Operation Manual

IMPORTANT
Ventilation:
A minimum building ventilation rate of 4 CFM per 1,000 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 ventila-
tion system,adequate fresh air into the building must be provided through fresh air
inlets and/or building inlets. It is recommended that state and local codes be
checked to assure the ventilation system and heat installation are in compliance
with state and local codes.
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 connec-
tions, 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:
l Periodically check the whole gas system for leaks or immediately check if
the smell of gas is detected. Extinguish all open flames.
l Never leak test while smoking.
l Do not use heater until all connections have been leak tested and do not
leak.
l When leak testing, refer to the connection diagrams.
l Only those parts recommended by the manufacturer should be used.
l Substitution can void warranty
Leak Test:
Make a soap solution of one part liquid detergent, and one part water. The soap
solution can be applied with a spray bottle, brush or rag. Soap bubbles will appear
where a leak is present. Turn the gas supply "ON". Turn the heater unit on and let
run on "HI". check for leaks at leakpoints. If a leak is present, turn off heater and
gas supply. Tighten any leaking fittings, turn unit on and recheck.
