Getting Started
A. Design and Installation Considerations
Heat & Glo direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.
No additional outside air source is required.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fire officials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
Before installing, determine the following:
• Where the appliance is to be installed.
• The vent system configuration to be used.
• Gas supply piping.
• Configuration of the required PowerFlow™ Heat
Management System(s). See Section 6.C.
• Electrical wiring requirements.
• Framing and finishing details.
• Which required power vent system will be used: PVI-
SLP-B or PVLP-SLP.
WARNING! Risk of Fire! PRIMO models must be power
vented using PVI-SLP-B or PVLP-SLP and have
PowerFlow™ Heat Management System installed and
operating when the appliance is turned on. Failure to
vent properly could cause overheating and fire.

Notes Regarding Passive Heat Option
•
Approved for use with these models ONLY: PRIMO48,
PRIMO48ST, PRIMO60, PRIMO60ST.
•
Approved for use ONLY with Clean Face Finishing
Option.
•
Hearth & Home Technologies recommends the PVLP-
SLP power vent option for use with the Passive Heat
Kit. If the application does not allow for the PVLP-
SLP to be used, the PVI-SLP-B may be used. The
PVI-SLP-B must be mounted outside the chase due
to the higher noise level created.
•
Because the Passive Heat option is naturally drafted,
it is the only PowerFlow
that operates automatically when the appliance is
turned on.
Installation and service of this appliance should be performed by
qualified personnel. Hearth & Home Technologies recommends
HHT Factory Trained or NFI certified professionals.

Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualified
service technician, service agency or your dealer.
