Regency® P42-4 Zero Clearance Direct Vent Gas Fireplace 9Position of Top Facing Supportfor material depth of 3/4” to 1-1/2"Top FacingSupportTOP ASSEMBLY &NAILING STRIPSThe Top Facing Support and Side Nailing Stripsmust be correctly positioned and attached beforethe unit is slipped into position.1) The top standoffs are shipped installed.2) The Top Facing Support and the 2 SideNailing Strips can be installed at differentdepths depending on the width of your facing.Match the depths of the top facing supportand the side nailing strips.a) Mount Top Facing Support using the 3supplied screws into the 3 pre-punchedscrew holes on the top front of the unit.See Diagrams 2 & 3 for the properposition of the Top Facing Support forthe various material depths.Diagram 1Diagram 2Diagram 3Diagram 4INSTALLATION5) The unit does not have to be completelyenclosed in a chase. The clearance on topof the unit from the top standoffs is 0" socombustible building materials can be laiddirectly on top of the standoffs. You mustmaintain these clearances from the ventto combustible materials: Flex Terminationclearance 1-1/2" (38mm), Simpson Dura-Ventclearance or (1-1/4" (32mm). Combustiblematerials can be laid against the side andback standoffs and the fireplace base.b) Mount the Side Nailing Strip using the 3supplied screws into the 3 screw holesor slots (diagram 4) on the side of theunit and repeat for the other side. Usethe hole for a 1/2" (13mm) thick facingmaterial and the slot for a range ofthickness from 3/4" to 1-1/2" (25mm to38mm).VENTINGINTRODUCTIONThe P42 uses the "balanced flue" technologyCo-Axial system. The inner liner vents productsof combustion to the outside while the outerliner draws outside combustion air into thecombustion chamber thereby eliminating theneed to use heated room air for combustion andlosing warm room air up the chimney.Note: These flue pipes must not beconnected to any other appliance.The gas appliance and vent system must bevented directly to the outside of the building,and never be attached to a chimney serving aseparate solid fuel or gas burning appliance.Each direct vent gas appliance must use it's ownseparate vent system. Common vent systemsare prohibited.VENT RESTRICTORA vent restrictor may be required. Checkthe diagrams in the "Rigid Pipe VentingArrangements" section to determine if the #6restrictor is needed for your vent confi guration.If required, attach the 2 piece #6 restrictorusing 4 screws per piece to the inside top ofthe firebox.Note: 43" (1092mm) is the minimum heightfor flex termination and Rigid Pipeterminations.Diagram 1FRAMING ANDFINISHING1) Determine the total thickness of facingmaterial (ie. drywall plus ceramic tiles) toallow the finished surface to be flush withthe front of the unit. Total facing thicknesscan vary from 1/2" (13mm) to 1-1/4" (32mm)thick.2) Frame in the enclosure for the unit withframing material. The framed opening forthe assembled kit is 36-5/8" high x 40-1/4"wide x 19" deep (930mm H x 1022mm Wx 483mm D). See Diagram 1.3) For exterior walls, insulate the enclosure tothe same degree as the rest of the house,apply vapour barrier and drywall, as perlocal installation codes. (Do not insulatethe fireplace itself.)4) The top louvers must not be closer than36" (914mm) to the ceiling.The HeatWave Duct Kit has differentclearance and framing requirements,check the HeatWave manual for details.
