4)  Assemble the desired lengths of Black Pipe 

and Elbows necessary to reach from the 
appliance adapter up through the support 
box and fl ashing to proper height as per 
Dia. 12, local codes.  Ensure that all pipe 
and elbow connections are in their fully twist 
lock position.

5)  Ensure vent is vertical and secure fl ashing to 

the roof  with roofi ng nails.  Slide the storm 
collar over the pipe section and seal with a 
mastic.

6)  Twist lock the vent cap on to the last sec-

tion.

Steep pitched cathedral ceilings may require 
the use of a support extension. This piece fi ts 
down inside the support and can be adjusted to 
increase the support's length by up to 22". The 
extension is attached to the support using the 
eight metal screws provided.  Be sure there is 
at least a 2 inch overlap where the extension 
joins the support.

This unit is approved in Canada for altitude to 
4500 ft. (CAN/CGA-2.17-M91). For Natural 
Gas installations above 4500 ft. follow current 
CAN/CGA-B149.1. 

The gas connection is a 3/8" NPT 90

o

 elbow. The 

gas line can be rigid pipe or to make installation 
easier, use a listed fl exible connector and/or cop-
per tubing if allowed by local codes. Since some 
municipalities have additional local codes it is 
always best to consult with your local authorities 
and the CAN/CGA B149 installation codes.

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 burner 
and/or valve servicing. Flare nuts for copper lines 
and fl ex connectors are  usually considered to 
meet this requirement.

If your home has a cathedral ceiling (no attic 
space between the ceiling and the roof), install 
the chimney and support as follows.

1)  Situate the chimney in a convenient loca-

tion as near as possible to the appliance 
outlet.  Cut and frame a hole in the roof for 
the support. The sides of this hole must be 
vertical with 1 1/4" clearance.

2)  Place the support in the opening. Lower it 

to the correct height as determined by the 
table and diagram below.

 

Using a level, make sure the support is 
vertical.  If the support extends above the 
roof, cut it fl ush with the top of the roof.  
Nail the support to the frame opening using 
(8) 3" spiral nails or #8 x 1-1/2" screws.

 Simpson 

Dura-Vent 

has 

provided 

angle 

brackets with this support which can be 
screwed to the outside of the support 
box and nailed to surrounding framing as 
required.  Use a minimum of four #8 x 1/2" 
screws per bracket.  In some cases these 
brackets may need to be trimmed (e.g.: 
to fi t under a fl ashing).  Place the Finish 
Collar around the support and fasten it to 
the ceiling using the screws provided.

3)  Use appropriate roof fl ashing.  Place the 

fl ashing under the upper shingles and on top 
of the lower shingles approximately half of 
the fl ashing should be under the shingles.
