CONNECTING SINGLE-WALL STAINLESS STEEL VENT TO THE HEATER
Metallic:
1. Order an optional appliance adapter kit,
(Pentair offers optional appliance adapter kits, call Customer Service)
:
- Part No. 77707-0086 for Saf-T Vent or Saf-T Vent CI. - Part No. 77707-0087 for Z-Vent. (UK only). To order
this optional adapter kit, please contact Pentair sales at Industriepark, Wolfstee, Toekomstlaan 30, 2200 Herentals -
Belgium.
2. Remove the outside vent cover.
3. Install the Appliance Adapter in the Vent Body of the heater (located under the outside Vent Cover). Before connecting
the Appliance Adapter to the Vent Body, wet a clean cloth or paper towel with isopropyl alcohol (rubbing alcohol)
and vigorously wipe the socket of the Vent Body. Immediately wipe the cleaned surfaces dry with a clean cloth or
paper towel. Repeat for the exterior of the heater end of the Appliance Adapter. Attach the appliance adapter to the
WARNING
Risk of carbon monoxide poisoning if adapter is improperly attached.
Mechanical connections (such as screws) can cause
cracking and leaks in the adapter. Do
NOT
drill holes or use screws to connect the appliance adapter to the heater vent body.
Attach with manufacturer’s specified adhesive.
WARNING
Risk of fire or asphyxiation if vent is not assembled according to manufacturer’s instructions or if vent parts from
different manufacturers are mixed.
Vent parts from different manufacturers ARE NOT interchangeable. Mixing parts from
more than one manufacturer may cause leaks or damage to vent. When installing a vent, pick one manufacturer and be sure
that all vent parts come from that manufacturer and are specified by the manufacturer for your system. Follow manufacturer’s
instructions and local code requirements carefully during assembly and installation.
4. Install vent pipe so that it can expand and contract freely as the temperature changes. Support the vent pipe according
to applicable codes and vent manufacturer’s instructions. Pipe support must allow the vent pipe free movement out
and back, from side to side, or up and down as necessary, without putting a strain on the heater or vent body. It is
recommended to slope the horizontal pipe down to condensate trap at least 2 cm/m (1/4 in per foot). Install “Approved”
condensate drains at low points where condensate might collect. Plumb condensate drains to a drain through hard
piping or high-temperature tubing such as silicone rubber or EPDM rubber – do not use vinyl or other low temperature
tubing. Follow drain manufacturer’s installation instructions.
5. Use an “Approved” firestop for floor and ceiling penetrations. Use an “Approved” thimble for wall penetrations.
Use an “Approved” roof flashing, roof jack, or roof thimble for all roof penetrations. Do not fill the space around
the vent (that is, the clear air space in the thimble or firestop) with insulation. The roof opening must be located so
that the vent is vertical.
6.
Vent Termination – Vertical
(see Figures 17, 18, 19 on page 15 & Figure 20 on page 16)
for height of vent
termination above the roof. Use an “Approved” vent terminal specified by local and national codes and your
manufacturer’s instructions. A roof termination must be vertical.
7. Make sure entire installation is sealed according to approved standard.
• at least 76 mm (3 in) and at most 304 mm (12 in) out from the wall (see Figure 24), following the vent manufacturer’s instructions
• at least 304 mm (12 in) above finished grade or the normally expected snow accumulation level, whichever is higher
• at least 1.2 M (4 ft) below or horizontally from, or 0.3 M (1 ft) above, any doors or windows or gravity air inlet to a building
• at least 0.9 M (3 ft) above any forced air inlet located within 3 M (10 ft)
• at least 1.2 M (4 ft) horizontally from electric meters, gas meters, regulators and relief equipment
• at least 2.1M (7 ft) above grade adjacent to walkways or similar traffic areas
Allow at least 1 M (3 ft) vertical clearance over vent termination when terminating under an overhang or deck.
Avoid corners or alcoves where snow or wind could have an effect. Exhaust may affect shrubbery and some building materials.
Keep shrubbery away from termination. To prevent staining or deterioration, sealing or shielding exposed surfaces may be required.
