Scalding
This water heater can deliver scalding temperature water at any
faucet in the system. Be careful whenever using hot water to avoid
scalding injury. Certain appliances such as dishwashers and
automatic clothes washers may require increased temperature
water. By setting the thermostat on this water heater to obtain
the increased temperature water required by these appliances,
you may create the potential for scald injury. To protect against
injury, you should install a mixing valve in the water system.
This valve will reduce point of discharge temperature by mixing
cold and hot water in branch supply lines. Such valves are
available from the local plumbing supplier.
Figure 6-1 Scald Warning Label Located on the Appliance
The following chart (Table 6A) details the relationship of water
temperature and time with regard to scald injury and may be
used as a guide in determining the safest water temperature for
your applications.
APPROXIMATE TIME / TEMPERATURE

System piping
System water piping methods
Observe a minimum of 1/4 inch clearance around all
un-insulated hot water pipes when openings around the pipes
are not protected by non-combustible materials.
General piping information
Basic steps are listed below along with illustrations on the
following pages (FIG.’s 6-2 thru 6-6), which will guide you
through the installation of the Armor X2 water heater.
1. Connect the cold water supply to the inlet side of the water
heater.
2. Connect the hot water supply to the outlet side of the water
heater.
3. Install a backflow preventer on the cold feed make-up water
line.
4. Install the factory supplied pump as shown in FIG.’s 6-2
thru 6-6.
5. Install an expansion tank on the system supply. Consult the
tank manufacturer’s instruction for specific information
relating to tank installation. Size the expansion tank for the
required system volume and capacity.
6. Install a drain valve at the lowest point of the system.
7. This appliance is supplied with a relief valve sized in
accordance with ASME Boiler and Pressure Vessel Code,
Section IV (“Heating Boilers”). Pipe the discharge of the
safety relief valve to a suitable drain to prevent injury in
the event of pressure relief. Pipe the discharge to a drain.
Provide piping that is the same size as the safety relief valve
outlet. Never block the outlet of the safety relief valve.
See the *piping illustrations included in this section, FIG.’s 6-2
thru 6-6 for suggested guidelines in piping the Armor X2 water
heater.
*Please note that these illustrations are meant
to show system piping concept only, the
installer is responsible for all equipment and
detailing required by local codes.
