Monessen Hearth TPB30, TPB24, TPB18 manual Clearances and Height Requirements

CLEARANCES and HEIGHT REQUIREMENTS

Heat resistant material (minimum requirements) with no wooden mantel or other combustible projection:

To install the gas logs into a fireplace with no wooden mantel, shelf or other combustible projection above the fireplace opening, measure the heat resistant material height, per Figure 5, then see TABLE A.

Heat resistant materials such as slate and marble must be at least 1/2” thick. Sheet metal should not be installed onto combustible material.

IMPORTANT: If you cannot meet these minimum clearances you must operate the heater with chimney flue damper open. Refer to “Installing Vented Applications” found on page 18.
