1. GENERAL
The Schwank gas fired infra-red combined intensity heaters are suitable to be installed for heating of outdoor and indoor spaces.
These installation instructions are intended for the patioSchwank Series 1100 Heaters. All installations in Canada must con-
form to local and national code requirements including the current CSA-B149.1-00 installation code for gas burning appliances
and equipment, and Canadian Electrical Code PART 1 CSA C22.1 latest edition must be observed. All installations in the U.S.
A. must conform to local and national code requirements including, National Fuel Gas code ANSI Z223.1 and the National
Electrical Code ANSI/NFPA No 70 (latest edition). Due to ever changing standards and requirements, revision to our equip-
ment and installation procedures may be necessary. In case of discrepancies, the latest installation manual will take priority.
2. INSTALLATION REQUIREMENTS
2.1 MOUNTING CLEARANCES
The patioSchwank Series 1100 Heater must be mounted with minimum clearances as shown in Section 8.3 and 8.4. It should
also be located with respect to building construction and equipment so as to provide sufficient clearance and accessibility for
servicing and cleaning of burners and ignition control.
2.2 HEATER MOUNTING
The patioSchwank Series 1100 Heaters are approved for both horizontal and angle mounting. When angle mount-
ing, the short axis may be rotated to a maximum of 30
o with venturi always in the upper position. Refer to Diagram
4 on Page 8. Improper angle mounting can result in damage to the heater or unsafe operation,
and will void warranty.
IMPORTANT: For either horizontal or angle mounting, the long axis of the heater must be level. Use only non-
combustible mounting hardware. Diagram 2 on Page 7 illustrates typical suspension hardware that may be used.
2.3 GAS SUPPLY LINE INSTALLATION
♦
All piping must be installed according to local codes.
♦
An approved flexible connector between the heater and gas piping must be installed. The same is available as an option
from Schwank.
♦
A drip-pocket at the inlet connection must be provided.
♦
On propane-fired units, a main line filter is recommended.
♦
Piping joint compounds must be resistant to the action of liquefied petroleum gases.
♦
All piping joints should be tested for leaks with a soap and water solution.
CAUTION: DO NOT INSTALL ANY GAS PIPING IN HEAT ZONES.
DO NOT SUBJECT HEATER CONTROLS TO LEAK
TEST PRESSURES WHEN CHECKING THE MAIN SUPPLY PIPING.
2.4 GAS PRESSURE
The maximum supply pressure must be limited to 14" W.C. (0.5 psi). If the line pressure is above 14" W.C., then a separate
pressure reducing regulator must be used. The minimum pressure at the inlet to the heater regulator must be equal to or greater
than 6.0" W.C. for natural gas and 11.0" W.C. for propane gas.
