Regency P33-3 Zero Clearance Direct Vent Gas Fireplace

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 connec-
tor. (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 fl ex 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.

1)  Maintain the 1-1/2" clearances (air spaces) 

to combustibles when passing through ceil-
ings, walls, roofs, enclosures, attic rafter, 
or other nearby combustible surfaces. Do 
not pack air spaces with insulation. Check 
pages 13-17 for the maximum vertical rise 
of the venting system and the 
maximum horizontal offset 
limitations.

2)  Set the gas appliance in its 

desired location. Drop a plumb 
bob down from the ceiling to 
the position of the appliance 
fl ue exit, and mark the location 
where the vent will penetrate 
the ceiling. Drill a small hole 
at this point. Next, drop a 
plumb bob from the roof to 
the hole previously drilled 
in the ceiling, and mark 
the spot where the 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 re-
stop.

 

pipe into the vent cap assembly. It is 
important that the vent pipe extends into 
the vent cap suffi cient distance so as to 
result in a minimum pipe overlap of 1-1/4 
inches. Secure the connection between the 
vent pipe 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.

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 suffi cient 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.

6)  Continue to assemble pipe lengths.

 
 

Galvanized pipe is desirable above the roofl ine 
due to its higher corrosion resistance. Continue 
to add pipe sections through the fl ashing until 
the height of the vent cap meets the minimum 
height requirements specifi ed in Dia. 4 or local 
codes.  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.

8)  Install the vertical termination cap by twist-

locking it.
