Hi everyone, I'm a total newbie at this since I just bought my first house so please bear with me: I have gas heating with force hot water, do I need to replace the filters (the oil filters) periodically? Do filters for my system even exist? I've taken some pictures, hopefully someone can help me identify...

Hi Fellas, Hoping someone can help me here with some good decisions. Getting closer to 60 yrs. I believe i will probably winter it out here until the end but one never knows. I am slowly remodeling and moving different house features around to make life more comfortable and more roomy inclusive to upgrading technology in this small 800 sq.ft. abode. There are a couple things i need to get resolved for planning this, so i am posting a drawing which will simplify my explanation of questions. New Furnace Bryant Plus 80 Model 310 5 Ton 110,000 BTU MODEL 310AAV 066110 AAJA Single Stage - Deluxe Induced Combustion 4-Way Multi-Poise 33" Tall x 21" Wide x 28"Deep (The old furnace is a Holly 80,000 BTu, from what i was told it is a "Standard Size " furnace, assuming 750 units were probably purchased above cost for 4 different floor plans in this sub-division, ranging from 2-4 bedrooms) I understand the new unit may be larger than sq. ft. needed,but i am also assuming that is, it's capable maximum output , and not what it normally runs at? The fact is that the furnace and "N" coil were $350, and are physically very small fitting my need. Space,Space,Space. I even almost went to tank-less gas hot water, but space restrictions make exhaust venting very temperamental (Carbon monoxide (CO) sensors) One of my big concerns is that i want to put in a newer central Heating - A/C system , removing the old unit out of it's closet establishment entire, and putting a new system out in the Garage/Shop in an dust proof type closet w/ conventional venting up through the attic space as is the old one. The new same style up-flow furnace setup will be mounted from the garage ceiling between trusses,hanging from the fire wall between the garage and living area, and the cold air return will be ducted from the corner living room through the fire wall, offset, and up to the furnace bottom, basically as it is set up now, but can detail all that later. My main concern questions are: 1) [QUOTE]Adequate gas supply[/QUOTE] It will add about approx. 25 ft of new line as shown in the drawing. Can you increase a 1/2 line up to a 3/4 line for more cu ft.? I believe the gas company stated that there is a 1/4 - 2 lbs. of available boost pressure at the meter? Keep in mind that this is slab-on-grade and that the existing gas lines are underneath and coming up through the floor plates and will have to tie into those taking the new lines across the truss chords. There is a new gas 60 gal GE Hot water tank and gas Jenn-Air cook-top.(See diagram) 2)[QUOTE]Type "B" venting[/QUOTE] to the back side of the roof (see diagram) Moisture Collection issues? 3)[QUOTE] Bryant "N" Coil; Up-flow - Down-flow [/QUOTE] Does it matter if it sits under the furnace in the cold air return stream or on-top, after the heat exchanger into the main trunk. I want to get this coil mounted into the main system and establish the rest later on, just for the sake of all the close quarter attic work. A 4/12 pitch truss system does not allow a lot of maneuverability. You can see for the most part what i am trying to achieve. My desire is to design this to code, basically mirror image to an extent what is already there, get a portion of it installed meaning the closet, furnace, trunk and coil, cold air return, then come back at another time with a mechanical permit and finish it out with the rest of the house. Money, and i need to get most of this physically out of the way for remodeling work while still using the old furnace system over the winter. The old system will be for the most part, pulled out at the end of the job, w/ new system inspected, then put into service. Everything then will have to be re-evaluated with the insurance company at the end for appropriate protection(s). Thanks for all the advice in advance, Cheers, Stuart [URL="[IMG]http://s6.postimg.org/6xfs0qerl/Natural_Gas_Locations.jpg[/IMG]"][IMG]http://s6.postimg.org/6xfs0qerl/Natural_Gas_Locations.jpg[/IMG][/URL]
