Installations With Vertical Termination-Through The Roof - Valor 534XAN Installation & Operating Instructions Manual

Installations with Vertical Termination—Through the Roof
All Co-Axial Vent Installations
• Check the roof pitch to determine which roof fl ashing will be needed.
See venting accessories list on pages 39–40 for allowable components.
• The distance from the roof to the lowest terminal discharge opening
("H" in fi gure 35) depends on the roof pitch and must be in accordance
with the manufacturer's instructions supplied with the termination unit.
Note: The venting system for these appliances is considered to be a
Special Venting System. The rule in the Installation Code requiring
a minimum vent height of 2' above any portion of a building within 10'
does not therefore apply.
• The minimum clearances to combustible materials all round the vent
pipes must be in accordance with the dimensions shown in the Location
section of this manual.
• Drop a plumb from the ceiling to the center of the appliance vent
opening. Mark the position on the ceiling. Drill a small hole at the
marked position.
• Determine the position where the vent will pass through the roof. If
directly above the position where it penetrates the ceiling, drop a plumb
from the roof to the small hole in the ceiling and mark the roof at this
spot.
If rafters or other obstructions will prevent a vertical exit or if clear attic
space is desired, the roof outlet can be offset using 45° elbows. See
fi gure 35.
Drill a small hole at the marked position.
• A ceiling fi restop must be installed at the second fl oor and higher fl oors.
A ceiling support should be used below the fl at ceiling.
To install the fi restop and support, cut and frame a 10" (254 mm)
square hole centered on the small hole previously drilled. See fi gure 36.
• Fit vent accessory elbows and pipe lengths as required
up through ceiling support boxes and fi restops.
If installation includes offset, support the offsetting pipes
every 3' (1 m) with wall straps. See fi gure 35.
• Cut a hole in the roof centered on the small hole.
The hole must allow for the minimum clearances to
combustible materials. See Location section in this
manual.
• Fit pipe lengths through the roof. Fit roof fl ashing
securing it with roofi ng nails.
• Fit storm collar and termination cap.
Co-Linear Vent Installations
• The chimney and fi replace opening sizes are shown in Dimensions and Location
sections of this manual.
• Place the appliance (fi tted with the co-linear adapter) near the fi replace opening but
allow space for manipulating the chimney liners on to the appliance.
• Drop the 3" dia. fl exible liners into the chimney from outside.
• Fit the liners to the co-linear adapter paying attention to inlet and exhaust and move
the appliance to its proper position. Be aware of the minimum liver bend radius and
maximum liner horizontal run shown on page 17 of this manual.
• Fit the termination kit and fl ashing to the exterior of the chimney.
• Secure the appliance to the fl oor or wall if necessary.
