Regency P33-LP4 Unit Installation With Vertical Termination, GAS Line Installation

INSTALLATION

8)Slide the appliance and vent assembly towards the wall carefully inserting the vent pipe into the vent cap assembly. It is important that the vent pipe extends into the vent cap sufficient distance so as to result in a minimum pipe overlap of 1-1/4 inches. Securetheconnectionbetweentheventpipe and the vent cap 3 sheet metal screws.

9)Install wall thimble in the center of the 10" square and attach with wood screws (Diagram 4).

4)Assemble the desired lengths of pipe and elbows. Ensure that all pipes and elbow connections are in the fully twist-locked position and sealed.

NOTE: For best results and optimum performance with each approved venting system, it is highly recommended to apply “Mill-Pac” sealant (supplied) to every in- ner pipe connection. Failure to do so may result in drafting or performance issues not covered under warranty. Silicone (red RTV) is optional.

5)Cut a hole in the roof centered on the small drilled hole placed in the roof in Step 2. The hole should be of sufficient size to meet the minimum requirements for clearance to combustibles of 1-1/2". Slip the fl ashing under the shingles (shingles should overlap half the fl ashing) as per Diagram 3.

8)Install the vertical termination cap by twist- locking it.

walls, roofs, enclosures, attic rafter, or other nearby combustible surfaces. Do not pack air spaces with insulation. Check "Venting" Sections for the maximum vertical rise of the venting system and the maximum horizontal offset limitations.

Note: Any closets or storage spaces, which the vent passes through must be enclosed.

GAS LINE

INSTALLATION

2)Set the gas appliance in its desired location. Drop a plumb

bob down from the ceiling to the position of the appliance

flue exit, and mark the location where the vent will penetrate

the ceiling. Drill a small hole at this point. Next, dropa plumb bob fromthe roof to the hole previously drilled in the ceiling, and

mark the spot where the	Diagram 1
vent will penetrate the roof.

3)A Firestop spacer must be installed in the fl oor or ceiling of every level. To install the Firestop spacer in a fl at ceiling or wall, cut a 10 inch square hole. Frame the hole as shown in Diagram 2 and install the fi restop.

Diagram 3: The upper half of the fl ashing is installed under the roofi ng material and not nailed down until the chimney is installed.

This allows for small adjustments.

6)Continue to assemble pipe lengths.

Note: If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet, to avoidexcessivestressontheelbows, and possible separation. Wall straps are available for this purpose.

Note that for steep roof pitches, the vertical height must be increased. A poor draft, or down drafting can result from high wind conditions near big trees or adjoining roof lines, in these cases, increasing the vent height may solve the problem.

7)Ensure vent is vertical and secure the base of the fl ashing to the roof with roofi ng rails, slide storm collar over the pipe section and seal with a mastic.

The gas line is brought through the right side of the appliance. The gas valve is situated on the right hand side of the unit and the gas inlet is on the right hand side of the valve.

The gas line connection may be made of rigid pipe, copper pipe or an approved fl ex connector. (If you are using rigid pipe, ensure that the valve can be removed for servicing.) Since some municipalities have additional local codes it is always best to consult with your local authorities and the CAN/CGA B149 installation code.

For USA installations follow local codes and/or the current National Fuel Gas Code, ANSI Z223.1.

When using copper or flex connectors use only approved fi ttings. Always provide a union so that gas lines can be easily disconnected for servicing. Flare nuts for copper lines and fl ex connectors are usually considered to meet this requirement.

Important: Always check for gas leaks with a soap and water solution or gas leak detector. Do not use open flame for leak testing.
