CONNECTING TO A GAS SUPPLY
The installer must supply the external regulator for liquid propane gas. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11" and 14" of water. If incoming gas pressure is not reduced, heater regulator damage will occur. Install external regulator with the vent pointing down.
You must also install a sediment trap. Locate the sediment trap where it is within reach for cleaning. A sediment trap filters moisture and contaminates. This also helps to keep the heater controls clean. If sediment trap is missing or installed wrong, your unit will not run properly.
