Prodigy Fireplace
Installation
Roof or Wall Mount Power Vent Installation
• Prodigy series replaces are certied for use with any
UL listed type B venting components. Use of other non-
certied parts will void the Montigo warranty, and may
impede the operation of the replace.
• The vent run should not exceed distances described in
Table 4. If your vent run does not meet these require-
ments please contact your local Montigo representative.
• Install components and ttings using the clearances
specied by the B-Vent manufacturer.
• All joints must be secured as per the instructions pro-
vided by the B-Vent manufacturer.
• The exhaust portion of a vent termination must not be
recessed in a wall cavity.
• Horizontal runs must be supported by a minimum of
three supports per 10 feet of venting.
• It is important that the location of the power vent motor
is not exposed to a downfall of water in excess of the
standard rain fall.
• Before installing the termination or venting, check to
ensure the planned termination location is acceptable.
Installing the Power Vent Termination
• Frame the chase for the Power Vent Termination to the
dimensions shown in Figures 13-15.
• Secure the termination and its frame using appropriately
rated fasteners.
Section 6: Power Venting
Inline Power Vent Installation
Installation from Fireplace to Power Vent (negative
pressure system):
• Prodigy series replaces are certied for use with any
approved UL certied type B venting components. Use
of other non-certied parts will void the Montigo war-
ranty, and may impede the operation of the replace.
• The vent run should not exceed distances described in
Table 4. If your vent run does not meet these require-
ments please contact your local Montigo representative.
• Install components and ttings using the clearances
specied by the B-Vent manufacturer.
• All joints must be secured as per the instructions pro-
vided by the B-Vent manufacturer.
• Horizontal runs must be supported by a minimum of
three supports per 10 feet of venting.
• Select a location for the power vent that will permit an
access panel for future maintenance work.
• Ensure access panel is large enough for the motor to be
accessed in case it ever must be removed.
• The power vent can be mounted to any solid non-com-
bustible surface.
• Anchoring bolts for the power vent should be rated for a
minimum of 300 lbs each and be 1/4”.
• If suspending the power vent, some bracing mechanism
should be designed to prevent any lateral movement of
the equipment.
Installation from the Power Vent to exterior of the build-
ing (positive pressure system):
• Beyond the inline power vent, piping must be pressure
stack rated with all joints sealed.
• For runs up to 30’, use Montigo VPIF piping. For runs
over 30’ Use a UL listed sealed pipe system.
• The exhaust portion of a vent termination must not be
recessed in a wall cavity.
• Horizontal runs must be supported by a minimum of
three supports per 10 feet of venting.
• The ue gas outlet should be a louver box or termina-
tion that has equivalent free air in square inches as that
of the ue collar.
Table 5: Allowable Exhaust Vent Runs
Min Vent
Run
Max Vent Run Elbows
3’ 80’
(including 7 elbows)
7 @ 90°
If more than 7 elbows are required, the maximum allow-
able vent run must be decreased by 20’ for each additional
elbow. For example, a vent run with 9x 90° elbows has a
maximum vent run distance of 40 feet.
Should your vent run fall outside of the parameters shown,
please contact a Montigo representative to discuss other
options.
