Planning your installation
General
Prior to starting your installation, we suggest you take the following into
consideration:
1. There are two possible ways to connect a direct vent venting system to a gas
appliance:
- Horizontal installation (through the wall);
- Vertical installation (through the roof).
Check the appliance manufacturer's installation instructions to see all possible
vent configurations.
2. Review all your options for the appliance location and also venting configuration.
Try to minimize the alteration and reframing of structural components of the
building (wall studs, water pipes, electrical wiring, ceiling joists, roof rafters, etc.).
It may be easier to change the location of your appliance than to modify the
building structure.
3. Carefully read the appliance and the venting system instruction manuals. Good
planning might save you time, work and money.
4. Use only authorized EXCELDirect

listed components unless compatibility with
another brand is specified in the appliance manufacturer’s instructions. Do not use
damaged parts.
5. For a horizontal installation, you will have to take into consideration the distance
between the gas appliance adapter to the wall, as well as the wall thickness and
a vertical rise (if applicable). The horizontal vent termination on the exterior must
be located in accordance with the Installation Codes and Regulations. See
"horizontal and vertical terminal location" section on page 20.
6. For a vertical installation, you must consider the distance between the gas
appliance outlet and the ceiling, the ceiling thickness, the height of the attic or
second floor and allow sufficient vent height above roof line. See Table 1 and
Figure 11.
7. For two-story applications, firestops are required at each floor. If an offset is
needed in the attic, additional lengths and elbows will be required.
8. Contact your local building authority and/or fire officials for permits, restrictions
and installation inspections. You may also wish to contact your house insurance
representative.
