FOREWORD

These designs comply with ANSI Z21.10.3/CSA 4.3 as an automatic 

circulating or automatic storage tank type water heater.

Heaters having an input of 305,000 (89 Kwh), 365,000 (107 Kwh), 

399,000 (117 Kwh) and 500,000 (147 Kwh) Btuh with a recovery 

rating of 277.3 gph (1049 Lph) or more also comply with ANSI 

Z21.10.3 as an automatic instantaneous type heater.

Detailed installation diagrams are found in this manual.  These 

diagrams will serve to provide the installer with a reference for the 

materials and methods of piping necessary.  It is highly essential 

that all water, gas piping and wiring be installed as shown on the 

diagrams.

Particular  attention  should  be  given  to  the  installation  of 

thermometers  at  the  locations  indicated  on  the  diagrams  as 

these  are  necessary  for  checking  the  proper  functioning  of 

the heater.

This model water heater is designed and manufactured in both 

natural gas and propane versions. MAKE SURE the gas on which 

the heater will operate is the same as that specified on the heater 

model and rating plate.

These heaters may be installed on combustible floors.

In addition to these instructions, the equipment shall be installed 

in accordance with those installation regulations in force in the 

local area where the installation is to be made.  These shall be 

carefully followed in all cases. Authorities having jurisdiction should 

be consulted before installations are made.

In the absence of local codes, the installation must comply with the 

current editions of the National Fuel Gas Code, ANSI Z223.1/NFPA 

54 and the National Electrical Code, NFPA 70 or CAN/CSA-B149.1, 

the Natural Gas and Propane Installation Code and CSA C22.1, 

the Canadian Electrical Code. All documents are available from 

the Canadian Standards Association, 8501 East Pleasant Valley 

Road, Cleveland, OH 44131. NFPA documents are also available 

from  the  National  Fire  Protection Association,  1  Batterymarch 

Park, Quincy, MA 02269.
