Multiple Unit Applications
(Vertical Direct Vent)
The combustion air inlet caps for multiple unit
installations
must maintain the minimum 2
foot (0.6m) clearance below the closest
vertical flue outlet if within 10 feet (3.0m).
Multiple flue outlet caps may be installed side by
side and multiple air inlet caps may be installed
side by side, but the air inlet
must always be at
least 2 feet (0.6m) below the closest flue outlet if
the outlet is within 10 feet (3.0m).
OUTDOOR INSTALLATION
Units are self venting and can be used
outdoors when installed with the optional
Outdoor Vent Kit. This kit includes a one piece
top cover which replaces the standard two
piece cover, air inlet cap, exhaust cap, gas
valve cover and junction box cover. The cap
mounts directly to the top of the water heater
and covers the flue outlet and combustion air
inlet openings on the jacket. No additional
vent piping is required. Maintain a minimum
clearance of 3" (76mm) to combustible
surfaces and a minimum of 3" (76 mm)
clearance to the air inlet.
An outdoor unit should not be located so that
high winds can deflect off of adjacent walls,
buildings or shrubbery causing recirculation.
Recirculation of flue products may cause
operational problems, bad combustion or
damage to controls. The unit should be located
at least 3 feet (0.91m) from any wall or vertical
surface to prevent adverse wind conditions from
affecting performance. Multiple unit outdoor
installations require 48" (1.22 m) clearance
between each vent cap. The outdoor cap must
be located 4 feet (1.22 m) below and 4 feet
(1.22 m) horizontally from any window, door,
walkway or gravity air intake.
The combustion air inlet of the outdoor cap must
be located at least one foot (0.30 m) above
grade and above normal snow levels. The water
heater must be at least 10 feet (3.05 m) away
from any forced air inlet and at least 3 feet (0.91
m) outside any overhang. Do not install in
locations where rain from building runoff drains
will spill onto the water heater. Lochinvar must
furnish an outdoor vent kit in accordance with
CSA international requirements. Each kit includes
the flue outlet/combustion air inlet, gas valve
cover, junction box cover and one piece unit top.
Freeze Protection- Outdoor Installation
A snow screen should be installed to prevent
snow and ice accumulation around the
appliance or its venting system.
If for any reason the unit is to be shut off:
(a.) Shut off water supply.
(b.) Drain unit completely.
(c.) Drain pump and piping.
If freeze protection is not provided for the
system, a low ambient temperature alarm or
automatic drain system is recommended.
