Monessen Hearth IDV490PVC Insert Installation, Check Gas Type, Internally tinned copper or copper

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

WARNING

A qualified installer or service person must connect appliance to gas supply. Follow all local codes.

CAUTION

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.

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.
