Regency B36X Manuel D’Utilisation

Regency Bellavista™ B36X  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 
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 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 ceilings, 
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.

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 restop.

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.

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.
