NOTICE: If your installation does not meet the mini- mum clearances shown, you must do one of the following:

•raise the mantel to an acceptable height

•remove the mantel

NOTICE: Surface temperatures of adjacent walls and mantels become hot during operation. Walls and mantels above the firebox may become hot to the touch. If installed properly, these temperatures meet the requirement of the national product standard. Follow all minimum clearances shown in this manual.

Figure 20 - Minimum Mantel Clearances for Built-In Installation

For propane/LP units, the installer must supply an external regula- tor. 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 point- ing down as shown in Figure 21, page 13. Pointing the vent down protects it from freezing rain or sleet.
