* Purchase the optional CSA design-certified equipment shutoff valve from your dealer.
The installer must supply an external regulator. The
external regulator will reduce incoming gas pressure.
You must reduce incoming gas pressure to between 11
and 14 inches of water. If you do not reduce incoming
gas pressure, heater regulator damage could occur.
Install external regulator with the vent pointing down
as shown in Fig. 12. Pointing the vent down protects it
from freezing rain or sleet.
Install sediment trap in supply line as shown in Fig.
11. Place sediment trap where it is within reach for
cleaning. Place 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.

you have the following items:
(2) Base Feet, (4) Sheet Metal Screws. (Fig. 13)
