GENERAL INFORMATION
C. PRE INSTALLATION REQUIREMENTS
The EVO MICRO is designed to be wall mounted using the supplied mounting
bracket or a factory supplied frame. Details are shown in Figure 1-3. The EVO
DUO must be installed using a factory supplied frame or rack system. The EVO
DUO is substantially heavier than traditional wall mounted appliances,
caution must be exercised when choosing a mounting surface if the leg
portion of a rack system is not used. Please see uninstalled unit weights
on page 5. It can be installed in alcoves, basements, utility rooms as well as
standard equipment rooms. Choose a location for your EVO, centralized to
the piping system, along with consideration for Electrical (Part 2, Page 8), Gas
Connection (Part 3, Page 10), Venting (Part 4, Page 14), and Condensate Drain
(Part 4, Section F, Page 20).
The EVO heat exchanger must be level as installed, and the mounting sur-
face must be designed to support the weight (see previous page, Table 1-1 for
weights). Be sure the appliance is adequately secured to the mounting surface.
The front cover is secured by a threaded screw and two clasp style latches; it
can only be installed one way. When removing the front cover of the EVO
unit, you must make sure all electric power to the appliance is turned
off. Then remove the screw at the bottom of the panel, undo the latches and
remove the cover (see Figure 1-4 on the next page).
If the EVO is set up for liqueed petroleum (LP) gas, some geographic areas follow the Uniform Mechanical
Code, section 304.6, “Liqueed petroleum gas burning appliances shall not be installed in a pit, basement or
similar location where heavier-than-air gas might collect. Appliances so fueled shall not be installed in a below
grade under-oor space or basement unless such location is provided with an approved means for removal
of unburned gas.”
