Fisher & Paykel DRH-48N manual Ventilation, Leak Test

INSTALLATION

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 con- junction with building ventilation system, adequate 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 codes.

When checking for gas leaks, do not use an open flame. Use a soap and water solution.

Note:

Gas connections on the heater are leak tested at the factory prior to shipment.

WARNING!

■Periodically check the whole gas system for leaks or immediately check if the smell of gas is detected. Extinguish all open flames.

■Never leak test while smoking.

■Do not use heater until all connections have been leak tested and do not leak.

■When leak testing, refer to the connections diagrams.

■Only those parts recommended by the manufacturer should be used.

■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” check for leaks at leak points. If a leak is present, turn off supply, tighten any leaking fittings, turn gas on and recheck.

Note:

There is a manual shut-off lever on the internal heater control valve/regulator. This lever is shipped in the “ON” position - Fig. 02 (Default position).
