Introduction
Installing The Fireplace
To install the fireplace:
The fireplace system is an engineered fireplace system, and will
require you to provide the correct vent run and air supply information
to the Engineering staff of Montigo.
After this initial consultation with Montigo we will specify the correct
power vent model for your project. The fireplace can be installed on
any combustible platform, as there will be no heat transfer to the base
of the fireplace
Fresh Air Supply:
Connect all of the fresh air supply for this fireplace to the lower vent
connections assuring no reduction or restriction to the air supply oc-
curs, even due to unexpected circumstances. Please consider auto-
mated dampers, particularly on the intake air supply in cold climates.
This is especially important when the intake air is introduced from the
top down. Cold air has the tendency to settle to the lowest point in the
vent system.
For extra long air supply runs, Montigo will recommend an increase in
vent diameter. When changing the air supply from several incoming
air connections to one vent, consult this information with your contact
at Montigo. To ensure adequate operation of the vent system ensure
the size of the one vent is not less than the total sum of vents that you
are connecting to.
Flue Gas vent run:
The fireplace system may be installed with any certified UL or ULC
B-Vent. All the clearances to this B-Vent must be equivalent to the
manufacture’s specifications as outlined in the installation/operation
manual. The size of this B-vent is specified in the approval process
and cannot be reduced unless Montigo has re-evaluated your system.
If authorized to reduce your vent size you will be issued new shop
drawings reflecting the new vent connection size and specifications.
The vent system may be installed vertically or horizontally, to any
length, and may have numerous elbows (information of quantity as
supplied to Montigo). Montigo will then re-evaluate this information
and size the Power Vent to the vent restriction, and compensate for
the pressure drop.
Power Vent:
Montigo manufactures a variety of Power vent modules as large as
5KWatts. The Power vent is commonly placed either horizontally or
vertically at the end of the B-Vent run. However, we have an in-line
vent module available. This Inline Power vent is for installations
where an exterior module isn’t visually attractive, or permitted.
Also, In-line Power vents are more complex to install, primarily due to
the positive pressure in the vent system after the Power vent module.
Therefore this vent run after the Power vent module must be air-tight
due too the concern gas by-products may leak from the vent into the
structure.
All Power vent modules create a negative pressure before the module
and leaks in the vent draw air from the building and will not create a
safety hazard.
