Figure 14 - External Regulator with Vent Pointing
Down (Propane/LP Only)
Use only new black iron or steel pipe.
Internally tinned copper or copper
tubing can be used per National
Fuel Code, section 2.6.3, providing
gas meets hydrogen sulfide limits,
and where permitted by local codes.
Gas piping system must be sized to
provide minimum inlet pressure (listed
on data plate) at the maximum flow rate
(BTU/hr). Undue pressure loss will
occur if the pipe is too small.
CAUTION
INSERT INSTALLATION
CHECK GAS TYPE
Use proper gas type for the insert you are installing. If you have conflicting gas type, do not install insert. See dealer where
you purchased the insert for proper insert according to your gas type.
INSTALLING GAS PIPING TO INSERT LOCATION
For propane/LP units, never connect insert directly to the propane/LP supply. This
burner system requires an external regulator (not supplied). Install the external regulator
between the burner system and propane/LP supply.
CAUTION
A qualified installer or service person
must connect appliance to gas supply.
Follow all local codes.
WARNING
INSTALLATION ITEMS NEEDED
Make sure you have the items listed below before installing appliance.
• External regulator (supplied by installer) • Piping (check local codes) • Sealant (resistant to propane/LP gas)
• Test gauge connection* • Sediment trap (optional but recomended)
• Tee joint • Pipe wrench
• approved flexible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certified equipment shutoff valve with
1
/8" NPT tap is an acceptable alternative to test gauge connection.
Purchase the CSA design-certified equipment shutoff valve from your dealer.
For propane/LP connections only, 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 13 inches of water. If you do not reduce incoming
gas pressure, burner system regulator damage could occur. Install external regulator with the vent pointing down as shown
in Figure 27. Pointing the vent down protects it from freezing rain or sleet.
