Masonry chimneys may take various contours which the exible liner will accommodate, however, keep the exible liner as straight as
possible, avoiding unnecessary bending but at all times keep a minimum of 3” (76 mm) inside bend radius.
The Air Intake Flex Liner must be connected to the inlet air
collars of the termination cap and the appliance.
The Exhaust Flex Liner must be connected to the exhaust
collars of the termination cap and the appliance.
The Air intake and Exhaust connections are marked on
the gas appliance. See picture.
DO NOT REVERSE THESE CONNECTIONS
CAUTION
To ensure that the venting is not accidentally obstructed
or punctured, the damper of the host replace must be
permanently disabled by either complete removal of the
damper, or by being fully blocked open, for the installation
of a gas replace insert. The 27-DVIM22N-2 requires (2) exible ue
liners:
INLET Collar - 3” (76 mm) diameter
OUTLET Collar - 3” (76 mm) diameter

Installation
Venting Instructions 999-INS-TK
Instructions for use with Archgard vertical termination cap. Part # 999-INS-TK
Install the termination cap being sure to provide su󰀩cient space (around and on top) so as not to impede the ow of air,
both into and out of the cap. This cap is only to be used for non combustible installations. Do not recess into the top of the
chimney.
1. Mark each end of one liner with “Air Intake”.
2. Mark each end of the second liner with “Exhaust”.
3. Pull the liner through the chimney.
4. Install the ashing.
5. Seal and attach the liner marked “Air Intake” to the vent terminal pipe marked “Air Intake” with the collar clamp provided.
6. Seal and attach the liner marked “Exhaust” to the vent terminal pipe marked “Exhaust” with the collar clamp provided.
7. Seal and attach the end of the ex marked “Air Intake” to the collar marked “Air Intake” on the appliance with the collar clamp
provided with the unit.
8. Install exhaust vent restrictors provided with the unit if required. Seal and attach the end of the ex marked “Exhaust” to the collar
marked “Exhaust” on the appliance.
9. Caulk all joints using a high temperature sealant such as milpac. DO NOT USE SILICONE SEALANTS. Use of silicon sealants
voids the warranty of the pilot assembly.
NOTE: The vertical termination cap must be sealed to the liner with suitable high temperature sealant, such as milpac and with the
hose clamps fasteners provided. DO NOT USE SILICONE SEALANTS (Use of silicon sealants voids the warranty of the pilot
assembly) The liners must form a complete connection from the appliance ue collars to the vertical termination cap.

Installation
Surround Installation
Surround options available are dependent upon the control panel conguration. (See Control Panel Locations regarding conguration.)
Shallow surround options are not available on a unit with ‘Controls Out’ conguration.
Make sure the gas and electrical lines are properly connected to the appliance. Slide the unit into the replace and slide the excess ue
liner material back onto the chimney. Before the appliance is fully recessed into the replace, attach the surround onto the appliance.
Attach the surround to the appliance at the locations shown by lining up the tabs on the surround with the slots on the unit. Make sure
the surround drops down and fully engages. Then nish with the wiring connection to the on/o󰀨 switch on the side of the trim. Now fully
“seat” the unit into its nal position.
Care must be taken that Trim Panels or Surrounds shall not seal ventilation openings in the replace.
