1. High Voltage Wiring Box
120VAC connections.
2. Removable Air Filter
Provides easy access and is easily removable for
inspection and replacement. 12”x20”high capacity
filter is rated MERV 8 (95% - 98% arrestance.)
3. Direct Vent Capability
Every XTherm is direct vent capable. By installing the
optional vent pipe adapter (D-18) and air plenum plug,
your XTherm is ready for direct vent. This makes it ideal
for storage of pool chemicals in the same room as the
XTherm. Damaging chemicals are not in contact with
the heat exchanger or combustion chamber.
3a. Outdoor Cover
If your job requires outdoor installation, an optional air
vent plug easily screws on to cover the direct vent air
intake. The combustion air will then be drawn from
inside the heater through screened plenum openings.
See photo above right.
4. Gas Inlet
The XTherm will operate at 100% full rate with gas
pressures as low as 4.0”w.c.
5. Water Outlet
6. Water Inlet
The XTherm can accept as low as 50°F continuous inlet
water temperature without damage to the primary heat
exchanger.
7. Access Panel to Cold Run Pump
Easily removable access panel even when unit is
plumbed in place. Provides full access to inspect and
service the Cold Run Pump system and condensate
drain switch.
8. Flue Outlet
The stainless steel flue outlet is compatible with AL29-
4C. For a dramatic cost reduction over Category IV
stainless steel, PVC or CPVC vent material may be used
in conjunction with the D-32 vent option.
9. Condensate Drain
3/4”NPT PVC connection for condensate removal.
Raypak offers optional condensate neutralizer kits (Z-
12) that can be plumbed between the heater and the
drain.
