WARNING
FIRE HAZARD
IMPROPER INSTALLATION CAN CAUSE
DEATH, SEVERE INJURY AND/OR
PROPERTY DAMAGE.
Refer to the following instructions as well as the
engineering drawing for proper installation of the
Reflect-O-Ray
®
EDS-4DI & EHS-4DI System.
INSTALLATION:
Installation must comply with local building codes, or in the
absence of local code, with the National Fuel Gas Code,
ANSI Z223.1- (current standard) - same as NFPA Bulletin
No. 54 for the United States and the CAN/CGA B149
(current standard) for Canada.
1. The wall penetration must be a minimum of:
a. 20' downstream of the burner for high fire inputs of
40,000 to 75,000 Btu/hr.
b. 25' downstream of the burner for high fire inputs of
80,000 to 125,000 Btu/hr.
c. 35' downstream of the burner for high fire inputs of
130,000 to 175,000 Btu/hr.
d. 45' downstream of the burner for high fire inputs of
180,000 to 250,000 Btu/hr.
2. A wall thimble suitable for 6", Type "L" vent (or better)
must be used.
3. Use an all-steel 6" type "L" vent duct (or better). The 6"
vent assembly must extend a minimum of 18" on either
side of the wall. Secure the 6" type "L" vent to the wall
thimble with sheet metal screws.
4. The Reflect-O-Ray
®
radiant tube should be positioned so
that it passes through the middle or center of the 6" type
"L" vent duct.
5. The reflectors, which are fitted with end caps, shall be
within one inch of the end of the 6" type "L" vent duct.
NOTE: The illustration below depicts a penetration
through a non-combustible wall. For penetrations
through combustible walls contact the factory for
