Boiler Piping for Hydronic Systems
Du to th d sign r quir m nts of th various
Wood Gun™ mod ls, th fiettaings and burn r
attaachm nts ar not always in th sam location on
ach boil r mod l. S App ndix A for th location
of th s attaachm nts. Theis diagram provid s xact
locations for all fiettaings. The flaush-out fiettaings in th
bottaom of th unit ar a r quir m nt of th ASME
boil r cod and must b clos d b for fielling th unit
with wat r.
Piping the Boiler in Parallel with Another
Boiler
The Wood Gun™ may b conn ct d to a h ating
syst m suppli d by on or mor boil rs that ar
alr ady in plac . To conn ct th boil r to th xisting
boil r run th supply pip with a flaow ch ck from th
Wood gun and T into th supply pip of th
xisting boil r. Theis pip will carry hot wat r to th
xisting boil r wh n th r is no h at d mand and
will in turn k p th xisting boil r from turning on.
The r turn pip with a circulator pushing toward th
Wood gun will T into th r turn lin of th xisting
boil r. It is r quir d that th piping b such that
xc ssiv pr ssur will not b d v lop d in any
portion of th boil r or syst m. The circulator will
constantly run wh n th Wood Gun boil r is on.
Wir th circulator to th Wood Gun boil r in such a
way that wh n th boil r switch is on th circulator
will also run. The pow r to th Wood gun should
th n b controll d by an aqua stat locat d in th
supply piping. Theis aqua stat should b s t 10ºF
abov op rating t mp ratur of th xisting boil r.
Theat will shut th Wood gun down if it runs out of
fu l. The aqua stat will n d to hav a bypass switch
that will allow th wood boil r to hav pow r and
nabl it to b start d so that it can b warm d to its
op rating t mp ratur .
The r ar many possibl confiegurations that allow
for an xisting boil r to function as a backup to th
Wood Gun™. For sampl illustrations of multipl
boil r confiegurations, s App ndix F.
Pressure Relief Valve
A pr ssur r li f valv should b ins rt d into
tapping DD on th Sup r E210.
Pressure Relief Valve
The purpos of xt nding th pip to th flaoor is
to dir ct any blowout of scalding wat r downward
inst ad of outward. Theis r duc s th lik lihood of
xposing bystand rs to a scald hazard.
Pressure Reducing Fill Valve
If th Wood Gun™ is install d as th primary
boil r, it is n c ssary to provid for wat r supply
using a pr ssur r gulating valv and back-flaow
pr v ntion valv in th f d wat r lin . S t th
pr ssur r gulating valv to 12-18psi.

Note: A length of ¾” copper pipe must be
connected to the pressure relief valve continuing
to a point 6 in from the floor as shown in Figure 3
above.
Note: Be sure to close all fittings in the unit
before filling the unit with water.
