[CentOS] Disabling Firewall/iptables on CentOS 7??

I apologize if this has been asked and answered, but I googled and 
attempted things for several hours today without success.

I have a freshly installed CentOS 7 system that I'd like to disable the 
firewall and all iptables rules. Basically the equivalent of doing 
iptables -F

In a nutshell I've tried the following commands, in many different ways 
and orders, but when the system restarts it still seems to end up with 
some form of default rules. It even has a couple rules specifying and I can't figure out where it's coming from.

#Disable Firewall
systemctl stop firewalld
systemctl disable firewalld
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm '/etc/systemd/system/basic.target.wants/firewalld.service'
systemctl disable firewalld
systemctl stop firewalld
iptables --flush
iptables --list
iptables -L
yum install iptables-services
service iptables save
systemctl enable iptables
service iptables save

Any help is appreciated.
