Installation
Step 8: Take the electrical harness (EPVH-10-100) that will commu-
nicate with the Power vent and pass the cable through the slot in the
rough box. Make sure the nut for the strain relief is inside the box and
the strain relief is outside the box.

Step 10: Push the molex connector through the hole in the electrical
cover until it clicks into place.

Step 11: Secure the electrical cover back down with the six screws
making sure the control cable curls up safely.
Figure 2m.
Step 12: Pass the vent pipe through the rough in box so it extends
6 1/2 inches into the rough in box.
Step 9: Reinstall the strain relief plate underneath the strain relief nut
and screw the strain relief plate down. Then tighten strain relief nut.

Step 16: Secure power head onto the rough in box with the supplied
4 screws. Make sure the power head makes good contact with the
gasket on the top and sides of the rough in box.
Step 15: Push the power head onto the vent. Make sure the power
cable for the power head does not get pinched or caught.

Step 14: Plug the power cable from the power vent head into the
control cable.
Step 13: Slip the Vent Support Band over the vent so that it sits ush
against the back of the rough in box. Tighten the band around the
vent so the vent cannot be pushed back through the hole in the rough
in box.

Appendix A: Warranty
The Warranty
The Companies warrants the Montigo Gas Appliance to be free from defects in materials and workmanship at the time of manufacture. On the Montigo replace,
there is a ten-year warranty on the rebox and its components, a ve-year warranty on the main burner and pilot burner, and a one-year warranty on the gas control
valve, bre logs and Power Vent Module. The Glass, plated / painted nishes, and refractory lining are exempt from the warranty.
Remedy And Exclusions
The coverage of this Warranty is limited to all components of the Gas Appliance manufactured by The Companies.
This Warranty only covers Montigo Gas Appliances installed in the United States or Canada.
If the components of the Gas Appliance covered by this Warranty are found to be defective within the time frame stated (see The Companies right of investigation
outlined below). The Companies will, at its option, replace or repair defective components of the Gas Appliance manufactured by The Companies at no charge,
and will also pay for reasonable labour costs incurred in replacing or repairing components. If repair or replacement is not commercially practical, The Companies
will, at its option, refund the purchase price of the Montigo Gas Appliance.
This Warranty covers only parts and labour as provided above. In no case shall The Companies be responsible for materials, components, or construction which
are not manufactured or supplied by The Companies, or for the labour necessary to install, repair or remove such materials, components or construction. All
replacement or repair components will be shipped F.O.B. the nearest The Companies factory.
Qualications To The Warranty
The Gas Appliance Warranty outlined above is further subject to the following qualications:
(1) The Gas Appliance must be installed in accordance with The Companies installation instructions and local building codes. The Warranty on this Montigo
Gas Appliance covers only the component parts manufactured by The Companies. The use of components manufactured by others with this Montigo Gas
Appliance could create serious safety hazards, may result in the denial of certication by recognized national safety agencies, and could be in violation of
local building codes. This warranty does not cover any damages occurring from the use of any components not manufactured or supplied by The Companies
(2) The Montigo Gas Appliance must be subjected to normal use. The Gas Appliances are designed to burn gas only. Burning conventional replace fuels such
as wood, coal or any other solid fuel will cause damage to the Gas Appliance, will produce excessive temperatures and will result in a re hazard.
Limitations On Liability
It is expressly agreed and understood that The Companies sole obligation, and purchaser's exclusive remedy under this Warranty, under any other warranty,
expressed or implied, or in contract, tort or otherwise, shall be limited to replacement, repair, or refund, as specied above.

exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. The duration of any implied warranty
with respect to this Montigo Gas Appliance is limited to the duration of the foregoing warranty. Some states do not allow limitation on how long an implied warranty
lasts, so the above may not apply to you.
Investigation Of Claims Against Warranty
The Companies reserves the right to investigate any and all claims against this Warranty and to decide upon method of settlement.

Appendix B: State of Massachusetts
Amendment
(Gas Fireplace / Equipment sold in the State of Massachusetts)
5.08: Modications to NFPA-54, Chapter 10
(1) Revise NFPA-54 section 10.5.4.2 by adding a second exception as follows:
Existing chimneys shall be permitted to have their use continued when a gas conversion burner is installed, and shall be equipped with a manually reset device
that will automatically shut off the gas to the burner in the event of a sustained back-draft.
(2) Revise 10.8.3 by adding the following additional requirements:
(a) For all side wall horizontally vented gas fueled equipment installed in every dwelling, building or structure used in whole or in part for residential purposes,
including those owned or operated by the Commonwealth and where the side wall exhaust vent termination is less than seven (7) feet above nished grade in
the area of the venting, including but not limited to decks and porches, the following requirements shall be satised:
1. INSTALLATION OF CARBON MONOXIDE DETECTORS. At the time of installation of the side wall horizontal vented gas fueled equip-
ment, the installing plumber or gas tter shall observe that a hard wired carbon monoxide detector with an alarm and battery back-up is installed on the oor
level where the gas equipment is to be installed. In addition, the installing plumber or gas tter shall observe that a battery operated or hard wired carbon
monoxide detector with an alarm is installed on each additional level of the dwelling, building or structure served by the side wall horizontal vented gas fueled
equipment. It shall be the responsibility of the property owner to secure the services of qualied licensed professionals for the installation of hard wired carbon
monoxide detectors
a. In the event that the side wall horizontally vented gas fueled equipment is installed in a crawl space or an attic, the hard wired carbon monoxide detector with
alarm and battery back-up may be installed on the next adjacent oor level.
b. In the event that the requirements of this subdivision can not be met at the time of completion of installation, the owner shall have a period of thirty (30) days
