SEDIMENT TRAP AND GAS LEAK CHECKS
A sediment trap kit is furnished with each heater and is to be installed by qualified contractor in accordance with
the manufacturer’s instructions and all codes and requirements of the authority having jurisdiction. Failure to
follow instructions could result in death, serious injury or property damage. The qualified contractor performing
this work assumes responsibility for this installation.
INSTALLING THE SEDIMENT TRAP
a)
When installing the gas line to the air heater, the sediment trap (see figure below) must be installed in the
gas line at a point before the air heater. The sediment trap must be installed vertical to properly function.
b)
This sediment trap or “drip leg” acts to trap impurities and water that can condense out of the gas. It
helps to keep impurities from entering the appliance and causing potential damage to gas valves, etc.
Periodically remove the cap from the drip leg and drain any accumulation of dirt and/or water.

GAS LEAK TEST
After all gas connections joints are made, perform the gas leak test using an approved leak detection solution at
the pipe. Bubbles forming indicate a gas leak. SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY.
Manual shutoff to the heater must be closed when pressure testing above 60 mbar.
