PRE-INSTALLATION

PREPARATION

Continued

1.Frame appliance enclosure as illustrated in Figures 7 and 8.

Note: If a wall covering is used to line the enclosure, then all measurements must be from the surface of the covering.

2.Place the appliance into the framing and secure it.

Note: If appliance is to be raised above floor level, a platform must be built to support the appliance.

3.Install the supply line to the appliance using a 1/2" NPT black iron gas line terminating 2 5/16" above the bottom of the appli- ance. The gas line must be installed through the lower left side access point or alternate access hole in the bottom of the appli- ance (see Figure 19, page 12).

4.Repack insulation around the gas line to cover any remaining openings in the conduit sleeve. Prepare the incoming gas line with teflon tape or pipe joint compound and hook-up incoming gas line to the flexible gas line.

Note: If 1/2" NPT black iron pipe does not mate with fitting at the end of flexible gas line, remove fitting and replace with a 37 degree flare 3/4"-12, 1/2" NPT (female) fitting.

These Dimensions Allow for a 3/4" Clearance at Sides and Back of Fireplace. However, 0" Clearance is Permitted

The transition pipe and starter collar shown in Figure 9 are supplied with the fireplace, unattached and ready for installation. Remove the starter collar and set aside. Slide the transition pipe over the vent collar and attach with a minimum of three screws. Replace the starter collar over the transition pipe and attach using four screws located on the leg stands (five used on the model M42). To install B-vent piping, slide the first piece of B-vent over the transition pipe and attach with a minimum of two screws.
