Fire Hazard. Do not vent the heater
directly into a masonry chimney. Installation into a
masonry chimney must use a chimney liner and must
meet National Fuel Gas Code requirements and all
local code requirements.

FIGURE 12: Typical Metal Vent Pipe Installation
(Vertical – Negative Pressure)
HORIZONTAL OR VERTICAL VENTING -
POSITIVE PRESSURE (See Figures 13 and 14)
Vent the heater either horizontally or vertically using one
of the 4-inch Special Gas Vent Pipes listed on Page 14
(Table 5). Install the vent pipe in accordance with local
codes and the provisions of the National Fuel Gas Code,
ANSI Z223.1, and the vent manufacturer’s instructions.
Do not use a draft hood with this heater. Use one of the
special gas vents specified in Table 5 (Page 14) for positive-
pressure venting of this heater – do not use any other vent
with it. Install the vent according to the vent manufactur-
er’s detailed instructions.
Maintain clearance between the vent pipe and combustible
surfaces according to the vent manufacturer’s instructions
and code requirements. Do not place any insulating mate-
rials around the vent or inside the required clear air space
surrounding the vent. See Table 6 (Page 15) for maximum
permissable vent lengths. See Table 7 (Page 15) for Listed
vent components.
CONNECTING SPECIAL GAS
VENT TO THE HEATER
Metallic:
1. Remove the outside vent cover as described on
Page 11.
2. Order an Appliance Adapter kit from Sta-Rite:
Part No. 77707-0086 for Saf-T Vent
or Saf-T Vent
CI.
®
®
Part No. 77707-0087 for Z-Vent.
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 alco-
hol (rubbing alcohol) and vigorously wipe the socket
of the Vent Body. Immediately wipe the cleaned sur-
faces dry with a clean cloth or paper towel. Repeat for
the exterior of the 4” end of the Appliance Adapter.
Attach the Appliance Adapter to the vent body using
the adhesive specified by the vent manufacturer, fol-
lowing the vent manufacturer’s instructions.
Risk of carbon monoxide poisoning if adapter
is improperly attached. Mechanical connections (such as
screws) can cause cracking and leaks in the adapter or
flue collar. Do not drill holes or use screws to connect the
appliance adapter to the heater vent body. Attach with
manufacturer’s specified adhesive.
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 interchange-
able. Mixing parts from more than one manufacturer may
cause leaks or damage to vent. When assembling a vent,
pick one manufacturer and be sure that all vent parts come
from that manufacturer and are specified by the manufac-
turer for your system. Follow manufacturer’s instructions
and local and National Fuel Gas Code requirements care-
fully during assembly and installation.
