We recommend that you install a sediment trap in
supply line as shown in Figures 21 and 22, depend
-
ing on your model. Locate sediment trap where it is
within reach for cleaning. Install in piping system
between fuel supply and heater. Locate sediment
trap where trapped matter is not likely to freeze.
A sediment trap traps moisture and contaminants.
This keeps them from going into heater controls. If
sediment trap is not installed or is installed wrong,
heater may not run properly.
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting
it to gas piping and/or fittings
(Variable Manually-Controlled
Models Only).
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting
it to gas piping and/or fittings
(Remote-Ready Models Only).
