We recommend that you install a sediment trap in
supply line as shown in Figure 14. 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 fireplace controls. If sediment trap is not
installed or is installed wrong, fireplace may not
run properly.
* Purchase the optional CSA design-certified
equipment shutoff valve from your dealer. See
Accessories, page 34.
