INSTALLATION REQUIREMENTS

1. Install and secure the vertical vent, gas vent or metal chimney according to manufacturer's
instructions or in accordance with NFPA 54 National Fuel Gas code or applicable local codes. The
termination of the vertical vent or metal chimney MUST be installed in accordance with the height
and roof pitch table (See Figure 1 or Table 1 or refer to NFPA 54 for requirements). These
minimum heights may be used if the vertical gas vent is not less than 8 feet from any vertical wall.
For other installations, the termination shall be not less than 2 feet above the highest point where
the vertical vent passes through the roof and at least 2 feet higher than any portion of a building
within 10 feet.

2. The vent termination MUST be at least 4 feet from or 1 foot above any window or opening into the

INSTALLATION

1. Before installation, apply two beads of high temperature
silicone sealant or equivalent around the bottom of the storm
collar and 1 inch above the end of the Starkap™ body. (See
Figure 2)

2. Insert the Starkap™ into the inside of the vent termination
pipe, making sure the Starkap™ is seated against the storm
collar. Fasten the Starkap™ to the vent termination pipe by
using three (3) sheet metal screws. Placement of the screws
should be approximately 1/2 inch from the end of the vent termination pipe. (See Figure 3) The
heads of the screws should be covered with high temperature.

SPECIAL VENTING APPLICATION INSTALLATION SHEET

This sheet covers the requirements for installation of the
Starkap™ for use with attached buildings designed for the
purpose of housing heating equipment outside of the living
space of the structure. These requirements are based on
A.G.A. test reports C-FT-5-90, C-FT-8-90, FT-C-12-93 AND
FT-C-13-93. See Figure 4 and 5.

1. The maximum gas heating appliance (or multiple
appliances ) up to 250,000 BTU/HR input.

2. Each appliance in the building MUST have its own separate
vertical vent and Starkap™.

3. The connecting wall between the attached building and the
main structure MUST be sealed to prevent flow into the
main structure. Example: Attached garages must be
sealed by lining ceiling and any wall adjacent to the living
space with 1/2" thick gypsum board or equivalent.
Openings from an attached garage directly into a room
used for sleeping purposes shall not be permitted. Other
openings between the garage and residence shall be
equipped with either solid wood doors not less than 1-3/8"
in thickness or 20-minute fire-rated doors, or equivalent.

4. Two make up/combustion air openings into the outside
building shall be installed. Size of the openings shall be 10
inch by 10 inch or based on 1 sq. inch per 4000 BTU/HR.

5. Termination location shall have a 4 ft. 9 in. center line
distance from any vertical wall up to 250,000 BTU/HR.
Termination location for up to 40,000 BTU/HR water heaters shall be a minimum 1 ft. 6 in. center
line distance from any vertical wall. A minimum height of 12 inches shall be maintained above the
roof.
