Turbotemp 125 Pool and Spa Heater Installation and User’s Guide
VERTICAL VENTING
(See Figures 21, 22 and 23)
Vent the heater vertically in a system in accordance
with AS/NZS 5601.1 and local codes. Double-wall vent
connector is recommended; however single-wall pipe
is allowed in some circumstances. Consult your local
code official for detailed information.
Do not
use a draft hood with this heater.
To connect a double wall metal gas vent to the heater,
order the appropriate Metal Flue Collar from the chart
below: See Table 6 to determine allowable vent sizes
for your heater.
1. STEP 1: See Table 6, to determine allowable vent
sizes for the Turbotemp 125 heater.
NOTICE: Table 6 is for installations in which the total lateral vent length (that is, the horizontal
distance from the flue collar to the main vertical portion of the vent) is less than half the total
vent height (the vertical distance from the flue collar to the vent termination) and which have
three or less elbows in the system. For vent lengths greater than 16 m (52.5 ft), only one elbow
is allowed. See Table 6a below for details.
Read “VERTICAL VENTING” above, before using this table.

1. See previous page for STEP 1 - See Table 6
(page 15), to determine allowable vent sizes
for the Turbotemp 125 heater.
2. Install the metal Flue Collar in the Vent Body
of the heater (located under the outside vent
cover). Fasten the metal Flue Collar to the Vent
Body with two #10 sheet metal screws. Use
high temperature silicone RTV to seal the Flue
Collar to the Vent Body. Before connecting
the metal Flue Collar 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 100 mm (4”)
end of the metal Flue Collar. Attach the
metal Flue Collar to the Vent Body using high
temperature silicone RTV, following the vent
manufacturer’s instructions.
