overhead doors, etc), structural components, and sprinkler system heads. Consideration must
also be given to ventilation fan placement (outdoor heaters do not require ventilation). Care-
fully survey the area to be heated, and for best results place heaters in the coldest area(s)
and at sufficient spacing to provide uniform radiant heat coverage.
Installation must conform with all local, state, provincial and national code requirements in-
cluding the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. The latest edition Elec-
trical Code ANSI/NFPA N0 70 in the U.S.A. must also be observed.
The heating system must have gas piping of the correct diameter, length, and arrangement to
provide for and satisfy the total system input. A layout drawing is necessary to calculate
properly sized gas supply piping.

6. INSTALLATION REQUIREMENTS

6.1 MOUNTING CLEARANCES

The SE+ Series Heaters must be mounted with minimum clearances to combustible materi-
als. Refer to the introductory section "Clearance to Combustibles" pages 6 to 10 and to Table
1 and Figure 1 page 7 (Outdoor) or Table 3 and Figure 3 page 10 (Indoor).
THIS HEATER HAS HOT SURFACES: Minimum mounting height is to be no less than 87"
above the floor / deck. Do not locate heater where patrons can come into contact with heater.
Do not store or place items directly underneath heater. Maintain clearance to combustibles.
The heater must be located with respect to building construction and equipment so as to pro-
vide sufficient clearance and accessibility for servicing of burner and ignition control and
cleaning . Provide adequate clearance around air openings into the combustion chamber.

6.2 HEATER MOUNTING

This heater must be rigidly mounted to prevent movement from wind force.
Refer to Table 2 and Figure 2. The SE+ Series Heaters are approved for both horizontal and
30° angle mounting on the short axis. Rinnai specifies a MAXIMUM 30° mounting angle - if
the short axis is rotated to an angle exceeding 30°, damage to the heater or unsafe operation
can result, and will void warranty.
IMPORTANT: For either horizontal or up to 30° angle mounting, the long axis of the heater
must be level. Use only non-combustible mounting hardware. Figures 6 & 7 on Page 21 il-
lustrate typical suspension hardware that may be used, and provided by Rinnai as an optional
component.
