fIGure 9.
Figure	9	shows	 the	typical	 attachment	 of	the	 water	 piping	 to	the	 water	
heater.	 The	water	 heater	 is	equipped	 with	1”	NPT 	threaded	 nipple	 
(75	 gallon	 models)	 or	1.25”	 NPT	threaded	 nipple	(100	gallon	 models)	
water	connections.
note:  If using copper tubing, solder tubing to an adapter before 
attaching the adapter to the cold water inlet connection.   do not 
solder the cold water supply line directly to the cold water inlet.  
It will harm the dip tube and damage the...

Water	 must	flow	from	 the	hot	water	 faucet	 before	 turning	 “ON”	gas	
to	the	water	heater.
To	fill	the	water	heater	with	water:
1. 		Close	 water	heater	 drain	valve	 by	turning	 handle	to	the	 right

clearance	 between	single	wall	vent	 pipe	 and	combustible	 surfaces	
with	 mortar	 mix,	cement,	 or	other	 noncombustible	 substance.	For	
other	 than	single	 wall,	follow	 vent	pipe	 manufacturer’s	 clearance	
specifications. 	To	 insure	 a	tight 	fit 	of 	the	 vent 	pipe	 in	a	brick	 chimney,

draft hood operatIon
Check	draft	hood	 operation	 by	performing	 a	worst	 case	
depressurization	 of	the	 building. 	With	 all	doors	 and	windows	 closed,	
and 	with 	all 	air 	handling 	equipment 	and 	exhaust 	fans 	operating 	such	
as	 furnaces,	 clothes	dryers,	range	hoods	 and	bathroom	 fans,	a

Because	of	the	 suddenness 	and	 amount 	of 	water, 	condensation 	
water	 may	be	diagnosed	 as	a	“tank	 leak”.	 	 After	the	water	 in	the	
tank	warms	up	(about	1-2	hours),	the	condition	should	disappear.
Do	 not	 assume	 the	water	 heater	 is	leaking	 until	there	 has	been 	
enough	time	for	the	water	in	the	tank	to	warm	up.
An	 undersized	 water	heater	 will	cause	 more	condensation.		 The	water 	
heater	 must	be	sized	 properly	 to	meet	 the	family’s	 demands	 for	hot	
water	 including	 dishwashers,...

You	should	 check	for	sooting.	 Soot	is	not	 normal	 and	will	impair	
proper	combustion.
Soot	 build-up	 indicates	 a	problem	 that	requires	 correction	 before	
further	 use.		Turn	 “OFF”	 gas	to	 water	 heater	 and	leave	 off	until	 repairs 	
are	 made,	 because	 failure	to	correct	 the	cause	 of	the	 sooting	 can	
result	in	a	fire	causing	death,	serious	injury,	or	property	damage.

In	replacing	the	anode:
1.	Turn	off	gas	supply	to	the	water	heater.
2.	Shut	 off	the	 water	 supply	 and	open	 a	nearby	 hot	water	 faucet	
to	depressurize	the	water	tank.
3.	 Drain	 approximately	 5	gallons	 of	water	 from	tank.	 (Refer 	
to 	“Draining 	and 	Flushing” 	for 	proper 	procedures). 	Close
